- Description
- A comprehensive photoluminescence and mechanoluminescence analysis of a ZnS:Mn2+ nano-phosphor with a zinc blende structure is presented. The sample containing quantum dot-sized nanocrystallites was synthesized by the chemical precipitation method and shows excellent orange luminescence at ambient conditions related to the 4T1 ? 6A1 transition. The sample shows stable and identical luminescence behavior under both UV and X-ray excitation at ambient conditions and also exhibits excellent self-powered mechanoluminescence properties. The pressure and temperature-induced luminescence mechanism of the phosphor is also established. The shift of the 4T1 ? 6A1 luminescence band of Mn2+ with both pressure and temperature and the luminescence mechanism is explained via the d5 Tanabe Sugano diagram. The broad luminescence band of the 4T1 ? 6A1 transition shifts from the visible to near-infrared range at a rate of ?35.8 meV GPa?1 with the increase of the pressure and it is subsequently quenched completely at a pressure of 16.41 GPa due to a reversible phase transition from zinc blende (F4?3m) to rocksalt (Fm3?m) phase. The high-pressure and temperature-dependent decay kinetics measurements of the sample luminescence are also reported. 2024 The Royal Society of Chemistry.
