摘要
采用化学溶液沉积法,在石英玻璃上制备了ZrO2∶Eu
3+,Y
3+(Eu-YSZ)转光膜,研究了Eu
3+、Y
3+掺杂浓度对薄膜的晶体结构、表面形貌和光学性能的影响。在波长为396 nm的紫外光和波长为466 nm的蓝光照射下,Eu-YSZ薄膜可发射出发光中心在593 nm和609 nm附近的红光带,这归因于Eu
3+离子的能级跃迁,且薄膜在可见光区间具有较高的透过率。研究表明,Eu-YSZ转光膜有利于减少短波蓝光对人眼视网膜造成的伤害。
Abstract
The ZrO2∶Eu
3+, Y
3+ (Eu-YSZ) light conversion films are prepared on the fused silica substrates by using the chemical solution deposition method. The effects of Eu
3+and Y
3+ doping concentrations on crystal structure, surface morphology and optical properties of thin films are investigated. Under the irradiation of ultraviolet light with a wavelength of 396 nm and blue light with a wavelength of 466 nm, the Eu-YSZ thin films show bright red emission bands centered at 593 nm and 609 nm, which are attributed to the energy level transitions of Eu
3+ ions. In addition, the thin films show a relatively high visible light transmittance. The study suggests that the Eu-YSZ light conversion films are beneficial to reduce the damage of short wave blue light to the retina of human eyes.
