C111 流体中の温度計測のためのTemperature Sensitive Particle開発(温度計測)

概要

Phosphorescence and fluorescence are often applied to measure the temperature and the concentration of oxygen. The intensity and the lifetime of phosphor depend on the temperature and the oxygen concentration, due to the quenching effect of the phosphor. The present study clarified the effects of temperature on the lifetime of phosphorescence of Ru (bpy)_3^<2+> and the europium complex. The phosphorescence lifetime and the other optical property of the small particles incorporated with the phosphor were investigated in the oil/water/air. The lifetime was strongly affected by temperature. Then, the temperature sensitive particle (TSParticle) with europium complex was applied to measure the temperature stratified flow two-dimensionally.
