The 19th International Conference on Luminescence (ICL2020) will be held in Changchun, China, August 10─14, 2020.

The 5th edition of Measuring By Light joins the 5th edition op OPTIMESS in a unique lustrum event.

The gathering will provide a platform where delegates of both Industry and Academia discuss novel measurement techniques and solutions, bridging requirements for both.

Simon Michels will give a presentation on "Luminescence as a novel optical NDT technique".

The ICU Congresses aim to bring together professionals and experts from academia and industry in all disciplines of ultrasonics, covering fundamental science as well as applications in the field of engineering material characterization and quality inspection, chemical and biological US based monitoring, medical imaging and therapy, etc. The ICU meetings provide a valuable and unique opportunity for participants to exchange their achievements and experience in view of addressing present-day challenges as well as to enlarge their international contacts on the field.

Our colleague Simon Michels will talk about "The thermal fingerprint of an ultrasonic beam: cheap and fast visualization".

The conference is devoted to all aspects of luminescence and luminescent materials. Novel fabrication technologies and techniques, studies of broadly understood optical properties of materials – single crystals, powders, sintered ceramics, nanostructures, glasses, amorphous systems – will be covered. State of the art of theoretical fundamental and applied research will be presented.

During the presentation "Infrared charge transfer luminescence in Eu-Tb co-doped sulfides" dr. Jonas Joos from LumiLab will talk about his relativistic ab initio calculations and the insight they provide in the experimental results.

The Photoluminescence in Rare Earths: Photonic Materials and Devices (PRE) workshop aims to provide a global forum for material scientists, chemists and physicists to discuss and debate the state of the art and future perspectives of rare earth based materials for optoelectronic and photonic applications. Fundamental aspects, properties, and applications of photoluminescent materials are considered.

LumiLab will be represented by prof. dr. Philippe Smet, with a plenary lecture on "Non-luminescent defects in solids: enemies or friends?", and dr. Jonas Joos who will give a talk about "Evidence for intervalence charge-transfer (IVCT) states in Eu-doped phosphors". 

This symposium provides an interdisciplinary forum for the presentation of the latest developments and breakthrough in fundamental researches and practical applications in the broad field of optical and optoelectronic materials, including material design technologies and crystal growth, structural and spectroscopic characterizations and application related issues.

Dr. Jonas Joos will talk about "Evidence for charge transfer (IVCT) states in Eu-doped phosphors: revealing their signature in absorption spectra".

The purpose of the conference is to bring together local and international scientists  who are working on various issues related to photonic materials. Following on the success of seven previous conferences in the series 'Kariega 2019' will take the same general format. In particular, the conference will focus primarily (but not exclusively) on the following material systems:

• III-nitrides such as GaN, AlGaN, InGaN, etc
• ZnO and other wide gap materials
• materials for photovoltaic applications, thermal photovoltaics etc
• biophotonic contibutions
• narrow gap materials for mid-infrared applications
• photonic crystals for fibre applications
• phosphors
• nano-materials for photonic applications
• novel photonic materials (including polymers)

Materials related issues that would fall well within the scope of the conference are the following:

• crystal growth and epitaxy
• characterisation (photoluminescence, DLTS, IR spectroscopy, etc.)
• defect related studies
• process related issues
• modelling of materials
• opto-electronic devices (novel structures, etc.)
• device modelling and characterisation

A group of international speakers, all experts in their fields, will present invited lectures on topics related to the theme of the conference. The scientific programme will also include a number of oral presentations selected from submitted abstracts, as well as poster presentations. Ample time will be available for the discussion of research results. As the number of delegates will be limited to less than 100, it is hoped that the conference will encourage much interaction, especially between local and international delegates.

At the 2019 Phosphor Global Summit and Quantum Dots Forum the latest developments in the industry will be discussed. Topics include OLED and LED lighting perspectives, new and emerging applications, ... Prof. Philippe Smet will talk about energy storage phosphors and their applications, from glowing roads to pressure memory.

Tijdens de kerstmarkt van de faculteit Wetenschappen kon men schenken voor het goede doel (De Warmste Week van Studio Brussel) om Stoneage Romeos het podium op te krijgen

De band met leadzanger Joeri Delamane (FDO Wetenschappen) is na meer dan 20 jaar opnieuw actief. Ze brengen old school Rock en Roll: Bowie, AC/DC, John Cale, Lou Reed, Iggy Pop, Patti Smith, Mink DeVille, Godfathers, Inmates, T-Rex, The Who, ... en een aantal eigen nummers.

Prof. Dirk Poelman van de vakgroep Vastestofwetenschappen is special guest tijdens dit optreden. Hij is momenteel druk aan het repeteren om een aantal nummers met de band mee te zingen.

Research on optically stimulated luminescence (OSL) of artificial materials has transformed the field of passive radiation dosimetry in the last 25 years. Today OSL is commercially used in personal radiation dosimetry in several continents, and active research is carried out worldwide on the underlying trapping and recombination processes of commercial luminescence materials and on the development new materials.

In addition to personal and environmental dosimetry, OSL dosimetry also plays a role in quality assurance in medical applications (diagnostic radiology and radiation therapy) and space dosimetry.

In this talk we will provide a personal perspective of the advances achieved in field in the last quarter of a century, from the development of Al2O3:C and the identification of BeO as dosimeters in the 90’s, until the development of new luminescence materials with properties tailored for OSL dosimetry and new applications.
