  Abstract


In this work, we developed a novel long afterglow material yttrium oxide doped rear earth by Combustion Method. The highlight of this work is the observation of bright red color tunable long afterglow of Y2O3:Eu3+,Ho3+. The structure information of the samples was studied in detail with X-ray diffraction. Photoluminescence and phosphorescence properties of the phosphor were investigated systematically. The reason why the photoluminescence and phosphorescence color can be tuned has been discussed. The bright long afterglow could be observed by naked eyes for 10s in the dark after ultraviolet irradiation was ceased. In this phosphor, Ho3+, Eu2+ ions doped in Y+ sites behave as luminescence centers, generate the defects serve as hole-trapping centers. In view of the experimental results, a feasible afterglow mechanism of Y2O3:Eu3+, Ho3+ was also proposed and discussed.
