Preparation and luminescent properties investigation of red and near-infrared emitting Mn4+, Ln3+-doped Al-based nano-fluoride phosphors Ghent University
Novel Mn4+,Ln3+-doped (Ln3+ = Eu3+,Dy3+,Tb3+,Sm3+,Yb3+,Er3+,Tm3+,Ho3+) Al-based with alkali metal, alkali earth metal or rare earth elements nano-fluorides will be prepared using a hydrothermal method. The emission positions will locate at red region based on the occupancies of Al3+ sites by Mn4+ and different regions for Ln3+ sites by alkali earth metal or rare earth elements originated from close ionic radius between them. Owing to the ...
