Pressure-enhanced and quantum-dot-activated photoluminescence in zero-dimensional organic metal halide hybrids family: Dual-channel modulation
Abstract
Lead-free zero-dimensional (0D) organic metal halide hybrids (OMHHs) offer exceptional structural and property flexibility for applications in electronics and optoelectronics. Here, a comprehensive investigation into the modulation effects of pressure and laser on a 0D OMHHs family was conducted. For TPP2MnCl4 ([(C6H5)4P]2MnCl4), high-pressure studies up to 10 GPa reveal competition between lp–π interactions and π–π stacking, accompanied by an 18-fold photoluminescence (PL) enhancement. In TPP2CuCl4 ([(C6H5)4P]2CuCl4), we first observe laser-activated orange PL with self-trapped exciton characteristics, originating from quantum dots (2–4 nm) generated by irradiation. Further investigation of thermal stability of TPP2CuCl4 PL showed its exceptional emission and structural thermal stability and potential application as a thermochromic material. This work provides new perspectives into the physical characteristics and advanced utilization of low-dimensional OMHHs.
