| 中文摘要 | the er(3+)-yb(3+)-li(+) codoped tio(2) powders have been prepared by sol-gel method. the strong enhancement of green and red upconversion emissions were obtained for er(3+)-yb(3+) codoped tio(2) by additional li(+) codoping and investigated using 976 nm semiconductor laser diode excitation. the enhanced upconversion emissions by the addition of li(+) resulted from the formation of li compound with lower crystal field symmetry. the fluorescence intensity ratio (fir) of green upconversion emissions from the transitions of (2)h(11/2) > 4i(15/2) and (4)s(3/2) -> (4)i(15/2) of era in the er(3+)-yb(3+)-li(+) codoped tio2 has been studied as a function of temperature in the range of 300-925 k, and the maximum sensitivity was determined to be 0.0025 k(-1). er(3+)-yb(3+)-li(+) codoped tio(2) material with the highest operating temperature up to 925 k, has higher temperature sensitivity and fluorescence efficiency being a promising candidate for applications in optical high temperature sensor. |
