摘要

对制备的分散在壳聚醣中ZnS:Mn纳米微晶的红外吸收光谱、X射线衍射谱、激发和发射光谱、发光效率、时间分辨光谱进行了研究

讨论了发光性质变化的原因。实验表明

纳米微晶中Mn

的弛豫时间比体材料减少了约2个数量级。通过测量结果讨论了振子强度的变化。

Abstract

The changes of excitation spectrum

emission spectrum

luminescence efficiency and the time resolved spectra of Mn

in nanometer-size ZnS clusters sticked to a chitosan medium were investigated. The causes of the changes of the luminescence properties have been discussed. Experiment shows that the decay time of Mn

in nanocrystals is shorter 2 orders than that of bulk ZnS:Mn. The oscillator strength of Mn ion radiative transition was disscussed according to these results of measurements.
