Abstract We consider a hybrid heterostructure containing an inorganic quantum well in close proximity with an organic material as overlayer. The resonant optical pumping of Frenkel exciton can lead to an efficient indirect pumping of Wannier excitons. As organic material in such hybrid structure we consider crystalline tetracene. In tetracene diffusion length of singlet exciton diffusion is strongly dependent on temperature. We have obtained the exact analytical solution of diffusion equation for exciton in organics at different temperatures defining different diffusion lengths of excitons. Then we have included in consideration Coulomb interaction between organics and QW. It was shown that this interaction multiple increases effectiveness of transfer from organics to QW in the same way as it was predicted early in our publications for inverse transfer from QW to organics. The effectiveness of energy transfer in hybrid with tetracene was calculated by definite method for two selected temperatures that opens possibility to operate in full region of temperatures. Temperature dependence of energy transfer in organics opens a new possibility to turn on and off the indirect pumping due to energy transfer from the organic subsystem to the inorganic subsystem. This varying pumping may be used for experimental investigating of different nonlinear effects.

混合有机物中的激子能量转移——半导体纳米结构

摘要 我们考虑一种混合异质结构，它包含一个与有机材料紧密相邻的无机量子阱作为覆盖层。弗伦克尔激子的共振光泵浦可以导致万尼尔激子的有效间接泵浦。作为这种混合结构中的有机材料，我们考虑结晶并四苯。在并四苯中，单线态激子扩散的扩散长度强烈依赖于温度。我们已经获得了在定义不同激子扩散长度的不同温度下有机物中激子扩散方程的精确解析解。然后我们考虑了有机物和 QW 之间的库仑相互作用。结果表明，这种相互作用倍数增加了从有机物向 QW 转移的有效性，这与我们在早期出版物中预测的从 QW 到有机物的逆转移相同。与并四苯混合的能量转移的有效性通过确定的方法在两个选定的温度下计算，这开启了在整个温度区域操作的可能性。由于能量从有机子系统转移到无机子系统，有机物中能量转移的温度依赖性为打开和关闭间接泵送开辟了新的可能性。这种变化的泵浦可用于不同非线性效应的实验研究。与并四苯混合的能量转移的有效性通过确定的方法在两个选定的温度下计算，这开启了在整个温度区域操作的可能性。由于能量从有机子系统转移到无机子系统，有机物中能量转移的温度依赖性为打开和关闭间接泵送开辟了新的可能性。这种变化的泵浦可用于不同非线性效应的实验研究。与并四苯混合的能量转移的有效性通过确定的方法在两个选定的温度下计算，这开启了在整个温度区域操作的可能性。由于能量从有机子系统转移到无机子系统，有机物中能量转移的温度依赖性为打开和关闭间接泵送开辟了新的可能性。这种变化的泵浦可用于不同非线性效应的实验研究。
