本文系统地研究了铀酰离子发光双指数衰减时的时间分辨发光光谱,测定和研究了相应条件下铀(Ⅵ)的激光拉曼光谱.通过计算机对所得光谱进行定量的拟合分解表明,铀(Ⅵ)的发光双指数衰减是两种发光体UO_2~(2+)和它的水解产物(UO_2)_2(OH)_2~(2+)发光叠加的结果。
In this paper, the time-resolved luminescence spectra of uranyl ion luminescence at double exponential decay were systematically studied and the laser Raman spectra of uranium (Ⅵ) under the corresponding conditions were determined and studied. The quantitative decomposition of the obtained spectra by computer shows that uranium The binary exponential decay of (VI) is the result of the superposition of the luminosities of UO_2 ~ (2+) and its hydrolysates (UO_2) _2 (OH) _2 ~ (2+).
