A possibility of low temperature measurement using fluorescence thermometry was examined. Temperature dependence of fluorescence lifetime applied to low temperature measurement. Chromium ion doped sapphire crystal (ruby) is known as a suitable sensor material for temperature measurement. Fluorescence thermometer using the ruby which is modified for temperature measurement has been fabricated. From this research, ruby crystal is found to be useful as the sensor head for fluorescence thermometer. In addition, the ruby crystal is potentially useful material for the sensor head crystals to measure low temperature below 273 K.

Chromium doped sapphire (Ruby) films have been fabricated on Si substrate by laser ablation, and their fundamental optical property and thermal characteristics are evaluated for temperature sensor application. The red emission near 700 nm which originates from 3d transition in Cr<SUP>3+</SUP> ions was clearly observed from the Ruby films. The split of PL peak, originated in 3d-orbital of chromium ion, is also clearly observed from Ruby films. Temperature dependence of PL spectrum from ruby films was measured under Ar laser excitation. PL intensity and PL peak positiongreatly vary with temperature ranging from 293 K to 443 K. To take the advantage of this phenomenon, the temperature sensor with calibration free can be developed.
