摘要:

 采用冷等静压-真空烧结技术制备尺寸为f10 mm×l mmEr:(Yb1–xLax)2O3陶瓷。通过分析粉体的X射线衍射谱和陶瓷的扫描电子显微镜照片,确定陶瓷制备条件为:在1 750 烧结20 h和在1 450 退火20 h。陶瓷样品在可见光波段透过率为50%左右,在近红外波段透过率最高达到82%。测试了陶瓷的吸收光谱、发射光谱和上转换发射光谱,并探讨了上转换发光机制。结果表明:陶瓷在977 nm处有强吸收,发射最强峰在1 545 nm处,上转换发出较强的绿光(542 nm)和蓝光(484 nm)

 Er:(Yb1–xLax)2O3 transparent ceramic sample with the size of f10 mm×l mm was fabricated by a cold isostatic pressing-vacuum sintering technique. The ceramic sample was characterized by X-ray diffraction and scanning electron microscopy. The sample could be prepared under optimal conditions (i.e., sintering temperature of 1 750  and sintering duration of 20 h, annealing temperature of 1 450  and annealing time of 20 h). The transmittance of ceramic in a visable bond is 50% and the maximum transmittance in a mid-infrared bond is 82%. The up-conversion mechanism of the sample was analyzed via absorption spectra, emission spectra and up-conversion emission spectra. The results indicate that the ceramic sample has a most intensive absorption at 977 nm, the strongest emission peak is located at 1 545 nm, and the up-conversion emission spectra show intense green and blue emissions.
