摘要：
The lasing spectra from a Rhodamine B-doped microdroplet (85% isopropanol and 15% water) with a thermochromic additive (CoCl2.6H(2)O) have been observed to shift progressively toward blue as the droplet temperature is gradually increased. The absorption of the thermochromic additive increases as the temperature of the solution is increased. The mechanism of temperature-dependent absorption is reviewed. We propose that the temperature-dependent shifting of the lasing spectra might be used far the determination of the droplet temperature. (C) 1995 Optical Society of America
