Uncovering the origin of radiationless losses in CuLaO2 by rationalizing the action of temperature and pressure on the luminescence Mikołaj Kamiński, Sebastian Mahlik, Anthony Barros and Philippe Boutinaud Abstract CuLaO2 is a rare-earth and dopant-free inorganic compound able to emit green light upon blue excitation. Its absorption amounts to 90% but its internal quantum efficiency is poor (< 17%).

Perylene diimide derivative dispersed in LDH as a new efficient red-emitting phosphor for LED applications Yixuan GUO, Damien Boyer, Federico Cisnetti, Anthony Barros, François Réverêt, Yongjun Feng, Genevieve Chadeyron and Fabrice Leroux Abstract Perylene diimide-based dyes substituted by four sulfonate groups at their bay position are known to be extremely sensitive to their mutual  –  intermolecular interaction. They do not emit fluorescence in solid state.
