| 摘 要： | 主要研究了环糊精(CD)体系,脱氧胆酸钠(NaDC)体系,溶胶-凝胶(sol-gel)体系在不除氧状态下溴代萘(BrN)的室温磷光现象,通过比较研究发现,不同体系之间存在一个共同点:各体系均能为磷光体提供一个相对刚性的环境,有效的阻止了双分子氧等猝灭剂对体系磷光的猝灭,通过各体系的磷光强度和磷光衰减特性比较发现,各体系的刚性化程度大小为:CD/BrN/环己烷>CD/BrN/金刚烷>NaDC/BrN>sol-gel/BrN,本文主要从氧的扩散过程入手,对抗氧猝灭的室温磷光进行了初步探讨。

| Abstract: | The RTP of the systems containing of cyclodextrin,NaDC,or sol-gel is observed.The common characteristics is that every system can provide a relative rigid microenvironment,which can prevent the phosphor from quenching by the oxygen and the other quenchers.It is found that the order of the rigidity degree of these system is as follows: CD/BrN/CH>CD/BrN/Ad>NaDC/BrN>sol-gel/BrN by the means of the measurement of the RTP intensity and lifetime.The mechanism of non-deoxygenated RTP is discussed preliminarily. |
