A measurement technique based on the lifetime method of two-photon induced luminescence was studied. Two-photon induced luminescence of temperature-sensitive dye was successfully observed by using pulse laser whoes pulse duration was of the order of pico seconds. Moreover, it was revealed that the lifetime of the luminescence was a function of temperature. Some dyes, such as quantum dots, were investigated as a novel temperature-sensitive dye to improve measurement accuracy.
