中文摘要the er3+-yb3+ codoped al2o3 has been prepared by the sol-gel method using the aluminium isopropoxide [al(oc3h7)(3)]-derived al2o3 sols with addition of the erbium nitrate [er(no3)(3) center dot 5h(2)o] and ytterbium nitrate [yb(no3)(3) center dot 5h(2)o]. the phase structure, including only two crystalline types of doped al2o3 phases, theta and gamma, was obtained for the 1 mol% er3+ and 5 mol% yb3+ codoped al2o3 at the sintering temperature of 1,273 k. by a 978 nm semiconductor laser diodes excitation, the visible up-conversion emissions centered at about 523, 545, and 660 nm were obtained. the temperature dependence of the green up-conversion emissions was studied over a wide temperature range of 300-825 k, and the reasonable agreement between the calculated temperature by the fluorescence intensity ratio (fir) theory and the measured temperature proved that er3+-yb3+ codoped al2o3 plays an important role in the application of high temperature sensor.
