New lanthanide-free self-activated full-color emission phosphor in Y doped Sr Bi(VO ) system for white light emitting diode applications.

Commercially used inorganic phosphors heavily depend on lanthanide doped host materials which are becoming more expensive and also their availability is limited due to scarcity. In this regard, a new lanthanide-free self-activated full-color emission phosphor in Y doped Sr Bi(VO ) system was developed by the conventional ceramic route. These phosphors crystallize into a hexagonal-type palmierite mineral structure.
