采用低温燃烧法合成出掺钕钇铝石榴石(Nd:YAG)粉末,经模压300MPa成型,于1700℃真空烧结5h,制备出尺寸φ9mm×1mmNd:YAG透明陶瓷片.对Nd:YAG透明陶瓷片进行光透过率、场发射-环境扫描电镜测量.采用体视学原理与方法定量地研究了Nd:YAG透明陶瓷的微观结构参数和光透过率之间的关系.研究结果表明:尺寸φ9mm×1mmNd:YAG透明陶瓷片在可见光波段光透过率约为45%,在近红外光波段约为55%;随着入射光波长的增加,光透过率增加;随着晶粒三维球当径(D3S)的增加,光透过率增加,当D3S约为20pm时,Nd:YAG透明陶瓷光透过率接近单晶理论值;随着晶粒以及单个晶粒平均比表面积的增加,光透过率降低;随着晶粒三维平均自由距离的增加,光透过率降低.
