摘要

以高纯Al

、Y

、Cr

和 CeO

为原料，采用固相法制备了Ce，Cr：YAG透明陶瓷。通过XRD测试和荧光测试，研究了0.5%Ce

，0.1%Cr

掺杂的YAG透明陶瓷片的晶相结构和光学性能。结果表明：1 750 ℃烧结获得的该陶瓷片为YAG纯相，在可见光区的透过率达到了70%以上。在430 nm的光激励下，透明陶瓷同时表现出了Ce

、Cr

的特征发射峰，在补充白光LED的红光部分方面具有一定的实际应用价值。

Abstract

Cr:YAG transparent ceramics were synthesized by solid state reaction method with high pure Al

and CeO

as raw materials. The crystalline structure and optical properties of 0.5% Ce

and 0.1% Cr

co-doped YAG ceramics were mainly studied by X-ray diffraction (XRD) and photoluminescence spectroscopy

respectively. XRD results show that the single YAG crystal phase is obtained when the precursor is sintered at 1 750 ℃. The linear transmission of the ceramic in visible range reaches about 70%. Under the excitation of 430 nm

the ceramic shows the characteristic emission peaks of Ce

and Cr

which might present it could be used in white-LED fields.
