Tuning phase transition and fluorescence quenching in 0D organic–inorganic hybrid materials by precise organic cation modification

exhibited complete fluorescence quenching. By combining different photoluminescent properties, the potential applications of these materials in anti-counterfeiting technologies were explored. This study offers new strategies for tuning phase-transition temperatures and luminescence performance in manganese-based materials, providing valuable insights for the development of low-toxicity and high-efficiency multifunctional materials.
