钕离子在聚合物介质中的可见吸收

UV-Visible Absorption of Nd￣(3+) in Organic Matrices

合成了三价钕的辛酸盐。采用溶液铸膜方法，制得含三价钕的聚合物固态薄膜样品。测得聚合物介质中钕离子的吸收光谱。与无机玻璃中的钕离子吸收进行比较，发现二者的^（４）Ｉ_（９／２）─^（２）Ｐ_（１／２）能级相差５ｎｍ。讨论结果表明：聚合物介质能保留稀土离子的吸收性质，可用于稀土发光材料的介质。

Neodymium octanate has been synthesized and dissolved in acetic acid and toluene containing poly(methyl methacrylate), respectively. The latter was used to make solid film sample by casting method. The UV-visible absorption of Nd3+ in organic matrices of different states had been measured and compared with each other and with that of Nd3+ in inorganic matrix. The difference of the spectra had been observed and the reason for it was discussed.
