INNOVATIVE LIGHTING USING MATERIALS WITHOUT LIMITED AVAILABILITY KU Leuven
Non-rare earth luminescent materials for displays and lighting Ghent University
The currently used luminescent materials for LEDs and diplays are based on the light emission of lanthanides. Due to their increasing cost and shortage, it is necessary to develop alternative materials,, especially for large light emitting surfaces. The project aims at investigating and developing such new materials. This is of fundamental importance, but also has a large economic potential.
Luminescent metal cluster confined in zeolites. Towards LED phosphor applications KU Leuven
The ever-growing demand for energy has led to an increasing pressure on the energy production, which in its turn has motivated research for more energy efficient products. An example of such products are light emitting diodes (LEDs). The implementation of LEDs as replacement for conventional lighting products, such as light bulbs and fluorescent lamps, is predicted to lead to a reduction of the global energy consumption for lighting by 50 % ...
LED and laser diode based illumination systems with a tuneable radiation pattern KU Leuven
The adoption of solid-state light sources for general lighting applications was mainly driven by the continuous need for efficiency improvements in the lighting industry. Most luminaires nowadays, make use of LEDs that can be easily dimmed if necessary. Introducing inexpensive sensors into these lighting fixtures can further reduce energy consumption by monitoring the environment and adjusting the illumination accordingly. A simple example ...
Boosting the optoelectronic performance of Perovskite Nanocrystals for LED applications KU Leuven
Organic-inorganic lead halide perovskites are semiconductor materials with outstanding optical properties, turning them into excellent candidates for devices employed in light-harvesting and emission. Perovskite crystals possess a large absorption coefficient and long charge carrier diffusion lengths, which is highly desirable for solar cell applications. For light-emitting diodes (LEDs), impressive progress in the photoluminescence quantum ...
A LED epifluorescence microscope with smart software to support department-wide research activities Ghent University
Conventional light microscopy remains one of the most widely used optical instruments in the sciences. Here, we apply for funding to obtain a versatile upright light microscope equipped with LED epifluorescence and transmitted illumination as well as optics that support brightfield, epifluorescence, dark field, differential interference contrast and crossed-polarised imaging. A high-resolution dual-mode (monochrome/colour) digital camera will ...
A New Metric for Evaluating the Colour Quality of White Light Sources with Reference to Memory Colours KU Leuven
Characterization of Microstructured Reactors for Photochemical Transformations KU Leuven
Photochemical reactions are found in a large variety of applications such as synthesis of pharmaceuticals, polymers, and water treatment. In the last two decades, photochemistry was coupled successfully with micro‑scale reactors accelerating the research of light‑driven organic synthesis. Nowadays, the photochemical reactions are carried out in both customized and commercial flow reactors which are predominantly illuminated by Light-Emitting ...
