Eu3+,Tb3+共掺杂NaY(MoO4)2材料的制备及发光性能研究
Synthesis and luminescence properties of NaY(MoO4)2:Eu3+, Tb3+materials
摘要
Abstract
Trivalent europium and trivalent terbium ions codoped NaY(MoO4)2 down-conversation luminescence materials were synthesized by hydrothermal method. The properties of NaY(MoO4)2:Eu3+, Tb3+ were characterized by X-ray diffraction, infrared spectrometer, excitation spectra and emission spectra. The effects of reaction temperature and the concentration of europium doping on the crystal structure and luminescence properties were discussed. The optimum synthesis conditions for NaY(MoO4)2 are as follows:the reaction temperature is 180 ℃, and the mole fraction of Eu3+is 0.7%. Under 395 nm excitation , the orange emission peak at 591 nm and red emission peak at 616 nm of NaY(MoO4)2:Eu3+, Tb3+can be observed. The emitting light results from the transition 5D0→7F1 and 5D0→7F2 of Eu3+, respectively. The sensitized effect of Tb3+to Eu3+and corresponding energy transfer were studied.关键词
