We have fabricated a temperature sensor which is characterized by fluorescence decay of quantum dots. In our previous work, we showed that the photoluminescence intensity of the quantum dots had negative correlation with the temperature. In this paper, the life time dependence of QDs on temperature was studied. Three kinds of ZnxCd1-xS alloyed quantum dots have been prepared and the life time of QDs was measured with temperature changed from 33 to 43 degrees C. As the temperature increased, the fluorescence lifetime of QDs decreased. This shows that temperature sensor based on life time change of QDs can be fabricated.
