Dy3+ -doped Y3 Al5 O12 phosphors were prepared at a relatively low temperature using molten salt synthesis. The phase of the prepared Dy3+ -doped Y3 Al5 O12 phosphors was confirmed using X-ray powder diffraction. Results indicated that Dy3+ doping did not change the Y3 Al5 O12 phase. Following excitation at 352 nm, emission spectra of the Dy3+ -doped Y3 Al5 O12 phosphors consisted of blue, yellow, and red emission bands. The influence of Dy3+ concentration and excitation wavelength on emission was investigated. The ratio of yellow light to blue light varied with change in Dy3+ doping concentration, due to changes in the structure around Dy3+ . Emission intensities also changed when the excitation wavelength was changed. This variation is luminescence generated a system for tunable white light for Dy3+ -doped Y3 Al5 O12 phosphors.

Dy3 +掺杂的Y3 Al5 O12磷光体的熔融盐合成和发光。

使用熔融盐合成法在相对较低的温度下制备了Dy3 +掺杂的Y3 Al5 O12荧光粉。使用X射线粉末衍射确认所制备的Dy3 +掺杂的Y3Al5O12磷光体的相。结果表明，Dy3 +掺杂不会改变Y3 Al5 O12相。在352 nm激发后，Dy3 +掺杂的Y3 Al5 O12磷光体的发射光谱由蓝色，黄色和红色发射带组成。研究了Dy3 +浓度和激发波长对发射的影响。黄光与蓝光之比随Dy3 +掺杂浓度的变化而变化，这归因于Dy3 +周围结构的变化。当改变激发波长时，发射强度也改变。这种变化是发光产生的，用于掺Dy3 +的Y3 Al5 O12磷光体的可调白光系统。
