| 中文摘要 | 采用熔融法制备Pr~(3+)掺杂的50ZrF_4-50(BaF_2-YF_3-AlF_3)-xPrF_3氟化物玻璃,系统研究了其在不同激发条件下的光致发光和闪烁发光性能。测试结果表明,Pr~(3+)位于可见波段、属于ff跃迁(~3P_0~3H_4、~3P_0~3H_6、~3P_0~3F_2等)的光致发光最佳摩尔分数为0.6%,并且随着Pr~(3+)浓度的增加,486 nm处的荧光寿命从56 ms下降到11 ms,浓度猝灭效应明显;而X射线激发时,最佳发光摩尔分数上升到1.0%。Pr~(3+)位于紫外波段的4f5d跃迁光致发光强度随着Pr~(3+)浓度的增加一直增强。这是由于4f5d跃迁能级差大,氟化物声子能量较低,而产生交叉弛豫需要很多声子,故难以发生浓度猝灭效应。当采用X射线激发时,检测到较强486 nm的发光,而未探测到紫外发光。 |
| 英文摘要 | Pr~(3+) doped 50ZrF_4- 50(BaF_2- YF_3- AlF_3)- x PrF_3 fluoride glasses are prepared through hightemperature melt- quenching method, and the properties of photoluminescence and scintillation under different excitation conditions are studied. Experimental results show that when excited by 443 nm blue light, the optimal luminous mole concentration of ff transition (~3P_0~3H_4, ~3P_0 ~3H_6, ~3P_0~3F_2) is 0.6 %; when excited by X- rays, the optimal luminous concentration is 1.0 %, and with the increase of Pr~(3 +) concentration, the fluorescence lifetime decreases from 46 ms to 21 ms, concentration quenching effect is quite obvious. The intensities photoluminescence of 4f 5d transition which locat in the ultraviolet band increase with the Pr~(3 +) concentration. This phenomenon is interpreted as that 4f 5d transition energy gap is quite large,while the phonon energy of fluoride glass is low, the cross- relaxation requires several phonons, so the concentration quenching effect is too difficult to occur. Under the X- ray excitation, the ultraviolet light doesn't be detected, while strong 486 nm light emission is generated. |
