阳极氧化铝膜的耐蚀性能及光学透射性王晓燕1,翟秀静1,张廷安1,郑双2(1.辽宁省沈阳市东北大学2.沈阳航空工业学院,沈阳 110032)摘 要:以硫酸电解液中阳极氧化制得的多孔氧化铝膜为研究对象,利用涡流测厚仪考察了不同pH值溶液中膜的耐腐蚀性,紫外测试分析了氧化铝膜的光学透射性.结果表明,氧化铝膜在中性及弱酸或弱碱性介质中耐腐蚀性能比较稳定.当pH值小于3时,氧化铝膜的失重率较高.当pH值大于11时,失重率也很大.波长小于360nm时多孔氧化铝膜的透射率较低,约10%以下,在波长360nm处曲线急剧上升,透......
Preparation and optical properties of Y2O3/SiO2 powderSHEN Xiaoyi and ZHAI Yuchun School of Materials and Metallurgy,Northeastern University,Shenyang 110819,China摘 要:optical properties of the Y2O3/SiO2 powder......
as a material system that can convert near-infrared light into visible/ultraviolet emissions by sequentially absorbing multiple photons. The studies on upconversion materials often use two rare earth(RE) ions as a sensitizer-activator pair. We investigated the influences on luminescence intensity depending on Cr-doping content(x) of hexagonal NaLu0.98-xCrxF4 Er0.02(x = 0-0.9)upconversion material......
