Luminescent behaviour of SrF2 and CaF2 crystals doped with Eu ions under different annealing temperatures

The photoluminescent (PL) properties of europium (Eu) doped SrF2 and CaF2 nanoparticles have been investigated after annealed in an Ar/H2 atmosphere at different temperatures for possible down-conversion applications in solar cells. PL investigations revealed that the Eu doped samples exhibited emis...
