Exploration of organic–inorganic hybrid perovskites for surface-enhanced infrared spectroscopy of small molecules†
Abstract
The organic–inorganic hybrid perovskites efficiently enhance the infrared absorption of small molecules. It is suggested that the quantum wells of perovskites enable the electrons of the perovskites to be excited by light in the infrared region. The exploration has opened a new path for chemical sensing through infrared spectroscopy.
