|
摘要
采用碳酸盐共沉淀法,制备了钬(Ho),铥(Tm):钇铝石榴石(YAG)透明陶瓷的纳米粉体.利用傅立叶变换-红外(FT-IR)光谱仪,热重-差热分析仪(TG-DTA),扫描电子显微镜(SEM)和X射线衍射仪(XRD)等先进的测试仪器对样品物相结构、表面特性进行了表征.实验数据表明,在经过1 000℃煅烧后,样品中形成了YAG的晶相,并且质量较为良好,纯度较高,形状较为规则,颗粒分散均匀,粒径均匀,粒径大小在70 nm～100 nm之间,790 cm~(-1),756 cm~(-1),728 cm~(-1),701 cm~(-1),667 cm~(-1),526 cm~(-1)处的吸收峰表明了YAG晶相的形成.结果表明,稀土离子Ho,Tm已经固溶进入YAG晶格中,可实现激光输出.
Nano-powders of Holmium(Ho),Thulium(Tm):Yttrium aluminum garnet(YAG) transparent ceramics were prepared by carbonate co-precipitation.The phase structure and surface properties of the samples were characterized by Fourier transform-infrared(FT-IR) spectrometer,Thermogravimetric-differential thermal analyzer(TG-DTA),Scanning electron microscope(SEM) and X-ray diffraction(XRD).The experimental results show that YAG crystalline phase is formed in the sample after calcination at 1000℃,with good quality,high purity,regular shape,uniform particle size,and the particle size is between 70 nm and 100 nm.The absorption peaks at 790 cm~(-1),756 cm~(-1),728 cm~(-1),701 cm~(-1),667 cm~(-1) and 526 cm~(-1) respectively indicate the formation of crystalline phase of YAG.The results show that rare earth ions Ho and Tm have been dissolved into YAG lattice and laser output can be achieved.
