Abstract
Transparent bulk glass ceramic containing nanoparticles was fabricated as an alternative for monocrystal to explore the possible application in fluorescence lifetime-based temperature sensing. Such glass ceramic exhibited deep-red luminescence upon the excitation of the wide wavelength range of visible light. Impressively, the lifetime dramatically decreased from 2.45 to 0.22 ms with the temperature increasing from 293 to 563 K, owing to the competition of radiation transitions from the thermally coupled and excited states. A two-level kinetic model was adopted to interpret this temperature-dependent luminescence of , which gave a highest temperature sensitivity of .
