| 中文摘要 | the er-mo:yb(2)ti(2)o(7) nanocrystalline phosphor has been prepared by sol-gel method and used as an optical thermometry. by mo codoping, the green upconversion (uc) emission intensity increased about 250 times than that of er:yb(2)ti(2)o(7) under a 976 nm laser diode excitation. it indicates that such green enhancement arises from the high excited state energy transfer (heset) with the i(2)f(7/2), (3)t(2)> state of yb(3+)-moo(4)(2-) dimer to the (4)f(7/2) level of er(3+). the fluorescence intensity ratio (fir) of the two green uc emissions bands was studied as a function of temperature in a range of 290-610k, and the maximum sensitivity and the temperature resolution were approximately 0.0074 k(-1) and 0.1 k, respectively. it suggests that the er-mo:yb(2)ti(2)o(7) nanophosphor with a higher green uc emissions efficiency is a promising prototype for applications in optical temperature sensing.
