近年来,随着激光、微弱信号测量以及瞬态测量技术等发展,对溶液中激发态离子的化学和物理行为的研究已日益受到人们的重视,激发态铀酰离子发光衰减的研究尤为活跃.Marcantonatos 等、Formosinho 等以及郑企克、王志麟等对高氯酸溶液中激发态铀酰离子的发光衰减过程进行了详细的研究.探讨了ClO_4~-溶液中pH 等对激发态铀酰离子的发光衰减的影响,观察到了一定的pH 条件下激发态铀(Ⅵ)的非单一指数衰减,并各自提出了不同的解释.值得提出的是,上述的一系列研究都是在高氯酸溶液中,其它体系中铀(Ⅵ)的发光哀减的研究进行得很少,报导则更少.1983年Joshi 等曾研究了80K 时SO_4~(2-)
In recent years, with the development of laser, weak signal measurement and transient measurement technology, the research on the chemical and physical behaviors of excited ions in solution has been paid more and more attention. The study on the decay of excited uranyl ion is particularly active. Marcantonatos et al., Formosinho et al., And Zheng Qi-Ke, Wang Zhilin et al. Studied the luminescent decay of excited uranyl ion in perchloric acid solution. The luminescent decay of excited uranyl ion in ClO 4 ~ - solution , A non-single exponential decay of excited uranium (Ⅵ) was observed under a certain pH, and different interpretations were put forward respectively.It is worth to be pointed out that the above series of researches all are in perchloric acid solution and other systems In uranium (Ⅵ) luminescence sorrow research carried out very little, reported less .Joshi et al 1983 studied 80K SO_4 ~ (2-)
