一般說明

氧化锗(VI),也称为锗或二氧化锗,是一种白色或灰白色粉末。它是一种高熔点(1600 °C)的难熔金属氧化物,具有优异的耐化学性。此外,氧化锗(VI)具有优异的光电性能,使其成为半导体工业中有价值的材料。它具有大约 2.1 的高折射率,比许多其他半导体材料的折射率高,并且具有低吸收系数。这些特性使其适用于波导、抗反射涂层和高折射率对比度涂层等应用。此外,锗(VI)具有约 3.1eV 的高带隙,并且在电磁光谱的红外区域中具有相对高的透明度,这使得它可用于红外探测器、LED 和太阳能电池等应用。

應用

无机纳米线的基材。用于合成超高折射率和超低损耗的光波导。

White solid-state light can be generated using three different approaches: By employing three diodes that emit red, green and blue light respectively, by using a near-UV LED that excites several phosphors that emit over the complete spectral range, or the third, most widely used alternative entailing down-conversion of a portion of blue LED light to longer wavelengths in such a manner that white light emerges.
