基于气固界面上能量转移催化发光气体传感阵列研究

This project presents a new strategy of gas sensor array based on gas-solid interface energy transfer cataluminescence. We want to carefully explore the cataluminescence emission of gas molecules and energy transfer mechanism of cataluminescence on the gas-solid interface, through the design and synthesis of luminescent materials with high catalytic activity, and obtain the tunable control catalytic luminescence spectra, and then establish the gas sensor array based on energy transfer cataluminescence with high performance for sensitive and selective detection of volatile organic compounds and other gas molecules. Compared with the traditional luminescence gas sensor, there would be more abundant spectral information, and we think this principle would improve the capability of gas sensing, and provide a new way for exploring the mechanism of molecular recognition at the gas-solid interface.
