Title:
ORGANIC PROTON-TYPE IONIC LIQUID, THIN FILM WITH TWO-DIMENSIONAL PEROVSKITE PURE-PHASE QUANTUM WELL STRUCTURE, PREPARATION METHOD THEREFOR AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2022/042529
Kind Code:
A1
Abstract:
An organic proton-type ionic liquid, a thin film with a two-dimensional perovskite pure-phase quantum well structure, a preparation method therefor and the use thereof. The chemical formula of an organic proton-type alkylamino acetic acid ionic liquid is RNH3 +·CH2COO-, wherein R represents different C4-8 alkyls or phenyls. The organic proton-type alkylamino acetic acid ionic liquid is preferably CH3(CH2)3NH3 +·CH2COO-. The organic proton-type alkylamino acetic acid ionic liquid can be used for preparing a perovskite material from an organic amine salt; and a prepared perovskite thin film can form a pure-phase single quantum well structure, and the grain size of the thin film reaches the micron level or even the millimeter level.
