Abstract: 

New functional materials for a wide range of applications multiplied in the last 20 years. Active lightning and/or optical devices are a important part of daily life (e.g. , LEDs) but frequently require organic compounds (prone to degradation processes), toxis elements or expensive raw materials such as rare earths, indium, ruthenium or iridium. The use of common and inexpensive raw materials (e.g., copper, sulfur) is key for future sustainability and development of devices such a solar cells,LEDs, chromic devices,etc, taking into account that e.g. rare-earths availability is predicted to be insufficient in the next 20 years. (…) The goal of the project is to develop new glass materials for down-converting UV light to visible/NIR light with luminescent quantum yields approaching unity.
