This project was conducted toward new type lasing device combined with a self-organized quantum well materials, lead halide-based layered peorvksite, and organic semiconductors. The results of this project are summarized as follows.1. Enhancement of electroluminescence (EL) efficiency by carrier confinement effect was attained in tri-layered device combined with lead halide-based layered perovskite with a self-organized quantum well structure as emissive layer and organic semiconductor layers. EL efficiency of tri-layered device of hole-transporting organic semiconductor/layered perovksite/ electron-transporting organic semiconductor is about 3 0 times that of double-layered device.2. We found enhancement of room-temperature exciton emission in lead halide-based layered perovskites by mixing of divalent metal such as Cd, Sn and so on. For example, room-temperature exciton emission intensity in PbBr-based layered perovskite mixed with 20 mol% of Sn was more than 5 times larger than that of corresponding pure PbBr-based layered perovsktite.3. We successfully prepared lead halide-based layered perovskite thin films by using the Langmuir-Blodgett technique. Employment of the Langmuir-Blodgett technique makes it possible to control film thickness and structure at the monomolecular layer level. Using the Langmuir-Blodgett technique, further, construction of microcavity device using lead halide-based layered perovskites as emissive layer was succeeded.

该项目是针对新型激光装置进行的，结合了自组织的量子井材料，基于卤化物的分层peorvksite和有机半导体。该项目的结果总结如下1。通过载体限制效应增强电致发光效率（EL）效率，在三层装置中与铅基于卤化物的分层钙钛矿相结合，具有自组织的量子井结构，作为发射层和有机半导体层。孔传输有机半导体/分层钙矿/电子传输有机半导体的三层设备的EL效率约为双层设备的3 0倍。2。我们发现，通过混合二价金属（例如CD，SN等）混合，在基于卤化物的层状钙蛋白酶中增强了室温激子的发射。例如，基于PBBR的层钙钛矿与20 mol％SN的室温激子发射强度比相应的纯PBBR分层钙钛矿大于5倍以上。3。我们通过使用Langmuir-Blodgett技术成功准备了基于卤化物卤化物的分层钙钛矿薄膜。 Langmuir-Blodgett技术的使用使得可以在单分子层水平上控制膜的厚度和结构。使用Langmuir-blodgett技术，进一步，使用基于卤化物卤化物的分层钙钛矿来构建微腔设备作为发射层。
