Structural Dimensionality Control of Organic-Inorganic Metal Halide Hybrids
Abstract
This project aims to develop and study novel organic-inorganic metal halide perovskites and hybrids with controlled compositions, structures, and dimensionalities. Its main thrust involves identification and understanding of phenomena and mechanisms associated with synthesis and processing of highly luminescent and stable metal halide perovskite nanocrystals, as well as organic metal halide hybrids containing various types of metal halide assemblies as the building blocks with three- (3D), two- (2D), one- (1 D), and zero-dimensional (OD) structures at the molecular level, which can display unique optical/electronic properties with potential applications in a variety of optoelectronic devices. During the third year of this project, we have achieved tremendous research progresses in the development and study of low dimensional metal halide perovskite hybrids from material development to device integration, with major accomplishments summarized as bellow. Synthetic control has been achieved for the preparation of OD organic metal halide hybrids containing a variety of metal halide molecular species and clusters. Multicomponent OD organic metal halide hybrids have been developed via proper crystal engineering. Photophysical tuning of OD organic metal halide hybrids from efficient phosphorescence to ultralong afterglow has been achieved by controlling the metal halides. Efficient light emitting diodes and X-Ray scintillators have been demonstrated using OD organic metal halide hybrids. Several graduate students and postdoctoral researchers have participated in this project and received interdisciplinary research training. The research in the third year has produced ten publications in high profile peer reviewed journals.
