摘要
报道了掺铥的重金属 -过渡金属氟化物 Tm :Ba Y2 F8粉体的制备及其频率上转换发光 ,在6 50 nm的红光激发下 ,样品可产生频率丰富的上转换发射峰 ,其中包括波长为 4 17nm,4 30 nm的紫光发射峰以及波长为 4 58nm,4 70 nm的蓝光发射峰。得到了 Tm3 + 离子在 Ba Y2 F8中的能级图 ,解释了其上转换激发与发射的机理。
The preparation of Tm∶BaY 2F 8 powders and the up conversion luminescence of Tm∶BaY 2F 8 are reported in this paper. Excited by red light of 650 nm, two violet luminescence with peaks at 417 and 430 nm and the blue luminescence with peaks at 458 and 470 nm were observed. According to the spectral data reported here, the energy level scheme of Tm∶BaY 2F 8 was given, and the mechanism of the up conversion luminescence was suggested.
