摘要: Single phase white light emitting CePO4 nanocrystals doped with Tb3+ and Sm3+ were synthesized through a sol gel route for the first time. The single monoclinic structure of samples was confirmed by XRD analysis. FTIR XPS analysis used to demonstrate that is good host minimum quenching environment. triple energy transfer processes from Ce3+ Tb3+, Sm3+via in are analyzed photoluminescence excitation emission spectra. role as bridge between ions systematically studied varying concentrations Sm3+. existence channels 5D3 5D4 levels revealed decay CIE chromaticity coordinates, color temperature high rendering index suggest newly developed cool co potential candidate field applications.
