phosphor can be prepared by SC method at 1ower temperature

and the morphology is much more uniform than the samples prepared by solid state (SS) method. Photoluminescence measurements show that the emission of the submicron sized Ca

phosphor presents a ~10 nm red shift compared with the SS sample

and the thermal quenching of the submicron sized Ca
