Pressure-enhanced and quantum-dot-activated photoluminescence in zero-dimensional organic metal halide hybrids family: Dual-channel modulation
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.
