摘要: Excitation dependent color tunable dysprosium and samarium co-doped cerium phosphate nanocrystals were synthesized via sol gel method. X-ray diffractograms confirmed that all the samples crystallized in monoclinic form. Morphology of resembling a custard apple surface was demonstrated by FESEM analysis. The structural characterization carried out FTIR XPS analysis displayed CePO4 lattice as good host providing minimum quenching environment. Luminescence characterizations done detail function Dy3+ Sm3+ doping concentrations means photoluminescence spectroscopy. Energy transfer from Ce3+ to established excitation spectra. possibility simultaneous activation ions utilized generate white light. luminescence measurements also explore yellow-white-orange- red tunability for different excitations. codoping with is found be more suitable generating light CIE values close standard stands potential candidate field applications.
