摘要：
Variations of fluorescence intensity ratio of green upconversion emissions in Er3+:Y2O3 nanocrystals and their bulk counterpart have been studied as a function of temperature. In the temperature range of 323-773 K, the maximum sensitivity of about 0.003 K-1 is obtained in the samples synthesized by the conventional sol gel method at 800 degrees C. It is found that the upconversion emission is enhanced by a factor of about 56 after re-calcining the conventional samples at 1300 degrees C. Besides that, the sensitivity is increased to the value of about 0.004 K-1, and the sensing accuracy is also improved. With efficient upconversion luminescence, high degree of sensitivity and accuracy, Er3+ doped Y2O3 bulk counterpart show promising application in nanoscale thermal sensor. (C) 2013 Elsevier B.V.
