Luminescence thermometry (LT) has emerged as a valuable technique for noncontact temperature sensing, with applications in real-time monitoring, microelectronics thermal management, and health surveillance. In this work, we developed temperature-sensitive material, potassium chloride(KCl):Sb3+, investigated its luminescent properties. The results indicated that the material exhibited broad excitation spectra within 250–400 nm wavelength range maximum at 366 showed band emission 590 upon excitation. Interestingly, demonstrated excellent responsiveness over of 273 to 373 K, which not been observed so far. To explore potential application measurement, utilized fluorescence intensity ratio (FIR) dual bands Sb3+ Tb3+ emissions (ISb/ITb) sensitivity KCl:Sb3+/Tb3+. an exceptional relative ambient temperatures 5.59% K–1 313 K. This study could potentially serve centers luminescence fields.
