ＨｆＯ２是一种优良的高折射率材料（在可见光区域折射率约为２），并且有良好的热稳定性，熔点也很高（约为２９００℃）．ＨｆＯ２在紫外波段的透过性也比ＴｉＯ２和ＺｒＯ２好，并且这个优点不是以牺牲它在可见波段、近红外及中红外的良好透过性能为代价的．因此，近年...
HfO2 is an excellent high refractive index material (with a refractive index of about 2 in the visible region) and has good thermal stability and high melting point (about 2900 ° C). HfO2 is also more transparent in the UV range than TiO2 and ZrO2, and this advantage is not at the expense of its good transmission in the visible, near-infrared and mid-infrared ranges. So in recent years ...
