Abstract
- Zero-dimensional (0D) organic–inorganic metal halide hybrids (MHHs) are considered promising luminescent materials due to their unique "host–guest" structure and tunable emission spectrum. Herein, we successfully prepared Sb<superscript>3+</superscript>-doped 0D (CH<subscript>6</subscript>N<subscript>3</subscript>)<subscript>3</subscript>BiCl<subscript>6</subscript> single crystals using an evaporation solvent method. The introduction of Sb<superscript>3+</superscript> results in a bright orange emission with a center wavelength of 610 nm. On increasing the Sb<superscript>3+</superscript> doping level to 20%, the doped sample achieves the highest photoluminescence quantum yield (PLQY) of 53%, attributed to the formation of self-trapped excitons (STEs) induced by the strong interaction between electrons and the crystal lattice. Interestingly, Sb<superscript>3+</superscript>-doped (CH<subscript>6</subscript>N<subscript>3</subscript>)<subscript>3</subscript>BiCl<subscript>6</subscript> exhibits rapidly reversible ethanol-responsive luminescence transition between orange and yellow emissions. This class of 0D MHHs exhibits high sensitivity and repeatability as a fluorescent probe for ethanol detection, demonstrating significant potential in environmental monitoring and ethanol detection applications.
