“Researchers have developed a self-recoverable mechanoluminescent phosphor Ca5Ga6O14:Eu3+, which can produce red light under stress and has good repeatability. By co-doping Tb3+, the color can be changed from red to green, providing a new direction for optical information encryption.”
“In the realm of micro and nanoscale temperature sensing, a breakthrough has been achieved with the development of a submicron-scale temperature sensor. This sensor, based on a triangular MAPbI3 nanoplatelet laser, exhibits an impressive sensitivity of 185 pm/℃. The linear shift in the laser line's peak wavelength with temperature changes enables accurate sensing. The sensor's high Q factor of ~2,610 and low laser threshold of 19.8 µJ·cm² underscore its potential for compact integration.”
