Abstract: Ce3+ doped Lu3Ga5O12 (LuGG∶Ce) nanophosphor was synthesized via co-precipitation method. Its structured parameters were obtained by Rietveld refinement method. The morphology of the as-synthesized nanophosphor was determined with Scanning Electron Microscope (SEM). Under 365 nm excitation, the emission spectrum exhibits an asymmetry broad band with central wavelength at 438 nm and this broad band can be deconvolved into two peaks with wavelength centers at around 426 nm and 470 nm, respectively. The chromaticity coordinate of LuGG∶Ce is (0.176 9, 0.180 3), which corresponds to blue light emission. The results show LuGG∶Ce is suitable for realizing blue light emission under UV excitation and thus has potential applications in the fields of UV-excited white light emitting diodes(LEDs).
