常见的有机发光体的发光过程有光致发光、电致发光和力致发光,它们都是单一过程的发光。合成了一种同时发双重颜色的蓝-黄发光体,通过对其溶液和固体发光光谱的详细对比、单晶结构分子内作用力的详细分析,研究了目标分子双重发光的原因,并通过对目标分子固体发光光谱的CIE色度计算,详细分析了该有机发光体的发光颜色。研究目标分子的磷光寿命,并应用在图案防伪领域。
As three kinds of common single optical processses,photoluminescence (PL),electroluminescence (EL) and mechanoluminescence (ML),have been well studied.The synthesis of a new organic luminophor that could emit both blue and yellow light was presented.And the cause of dual luminescence of the target molecule was detailedly analyzed by the comparision of solution and solid luminescence spectrum,and the analysis of intromolecular action.Further more,the target molecular calculation of CIE chromaticity of the solid photoluminescence spectrum was also performed to study the orgainc luminophor's emitting color.the phosphorescence lifetime of the target molecule was studied,and applied it to pattern anticounterfeiting.
