PtOEP has been used in dissolved oxygen sensors as excellent indicators for its good fluorescent properties. In this paper, we mainly studied the temperature effect on the PtOEP embedded in sol–gel film after confirming that the fluorescence emitted from PtOEP can be quenched by oxygen, and found the fluorescence intensity of PtOEP decreased with the rise of temperature. Then a quadratic polynomial which can be a good description of the relationship between the fluorescence intensity and temperature was given out. At last, analysis of the temperature influence on the dissolved oxygen sensor precision was presented.
