| 英文摘要 | A series of yb3+/er3+ codoped transparent oxyfluoride glass ceramics with various amounts of yb3+ have been successfully fabricated and characterized. under 980 nm laser prompting, the samples produce intense red, green and blue up-conversion emissions, and the emission intensities increase with yb3+ concentration and heat treatment temperature. before losing good transparency in the visible region, optimum emission intensities are obtained for the sample with 25 mol% of yb3+ at a heat treatment temperature of 680 degrees c. a possible up-conversion mechanism is proposed from the dependence of emission intensities on pumping power. the fluorescence intensity ratio between the two thermally coupled levels h-2(11/2) versus s-4(3/2) was measured with the laser output power of 57 mw to avoid the possible laser induced heating effect. the fluorescence intensity ratio values in the temperature range from 295 k to 723 k can be well fitted with the equation: a exp (-delta e/k(b)t), where a = 6.79 and delta e=876 cm(-1). the relative temperature sensitivity at 300 k was evaluated to be 1.4% k-1. all the results suggest that the yb3+/er3+ codoped caf2 glass ceramics is an efficient up-conversion material with potential in optical fiber temperature sensing.
