高效的给-受体(DA)能量传输材料体系被公认为有机激光器中的重要组成部分。基于Frster传输和受激发射的理论
我们提出了一种在DA系统下发射光谱的数值模型。该模型较好地描述了在DA材料系统中发射光谱随着受主浓度变化的最主要特征
即光致发光谱峰值波长随着受体浓度的增加而非线性增大
并在浓度较高时趋于受体的单体发射波长。
Efficient donor-acceptor (DA) energy transfer material systems are considered to be the candidate for organic lasers. We developed a numerical model for the emission spectra of DA systems based on the theory of Frster energy transfer and stimulated emission. The model describes the essential emission spectrum features related on the acceptor concentration in theoretical DA system
in which the monomer wavelength of the photoluminescence increases none linearly with the acceptor concentration
and tends to reach the monomer emission wavelength of acceptor at high acceptor concentration.
