Sr <sub>5</sub> (PO <sub>4</sub> ) <sub>3</sub> Cl:Mn <sup>5+</sup> solar-powered luminescent thermometer with the potential for lunar soil temperature measurement
Scientific research and measurements conducted on the Moon are significantly constrained by electricity shortages. Consequently, the development of low-power or even zero-power devices and sensors has become an urgent priority. Our research has revealed that the Sr<sub>5</sub>(PO<sub>4</sub>)<sub>3</sub>Cl:Mn<sup>5+</sup> phosphor exhibits a distinct property: it can absorb sunlight and emit near-infrared (NIR) light. When Sr<sub>5</sub>(PO<sub>4</sub>)<sub>3</sub>Cl:Mn<sup>5+</sup> is used as a solar-powered luminescent thermometer (SPLT), it eliminates reliance on any energy sources other than sunlight; by contrast, traditional luminescent thermometers require excitation via electricity-driven light sources. This unique characteristic endows it with significant advantages for applications in electricity-scarce environments. Additionally, the SPLT with remote sensing capabilities is expected to solve the challenge of directly observing lunar soil temperature from Earth when combined with ground-based observation.
