Hybrid photonic crystals - Co-assembly of conjugated polymer particles in a Perovskite Matrix

提出了一种基于钙钛矿基质中的共轭聚合物粒子组装的无机/有机复合光子学的新方法。单分散共轭聚合物粒子及其在介电基质中的组装已在先前的项目(KU 2738/3-1)中开发。这个后续项目的重点是这些粒子在半导体钙钛矿基质中的胶体自组装。各组分的吸收和发射带将以这样的方式排列，所得到的结构允许对钙钛矿进行光泵浦，随后能量转移到组装的共轭聚合物光子晶体，从而导致有机成分的激光发射。我们将研究从无机到有机材料的级联能量转移机制。这一认识将是实现从光泵浦有机激光器向电泵浦战略过渡的重要一步。

A new approach for hybrid inorganic/organic photonics, based on conjugated polymer particles assembled in a Perovskite matrix, is proposed. Monodisperse conjugated polymer particles and their assembly in a dielectric matrix have been developed in a previous project (KU 2738/3-1). This follow-up project focusses on the colloidal self-assembly of these particles inside of a semi-conducting Perovskite matrix. The respective absorption and emission bands of the components will be aligned in such a way, that the resulting structure allows for optical pumping of the Perovskite, followed by an energy transfer to the assembled conjugated polymer photonic crystal resulting in laser emission from the organic component.We will investigate the cascaded energy transfer mechanism from the inorganic to the organic material. This knowledge will present an important step towards realizing the transition from optically pumped organic laser towards strategies for electrical pumping.
