摘要

文章采用固态反应法制备了Co²⁺掺杂的YAG透明陶瓷，旨在探讨其在深紫外探测领域的应用潜力。为此，系统研究了样品在深紫外光激发下的光谱性能。重点分析了深紫外光激发下的发射光谱，以及光谱强度（峰值和积分）与激光激发条件（重复频率、单脉冲能量和激发光斑尺寸）之间的线性响应关系。实验结果表明，样品在深紫外光激发下呈现出峰值波长541nm的窄带（FWHM=45nm）荧光发射光。此外，该材料的光谱强度（峰值和积分）与激光激发条件（重复频率、单脉冲能量及激发光斑尺寸）的线性相关性均大于0.97，表明该材料的荧光转换信号强度与入射能量强度呈良好的正比关系，在深紫外探测领域展现了Co²⁺:YAG透明陶瓷良好的应用潜力。

Abstract

doped YAG transparent ceramics were fabricated by the solid state reaction method

aiming to explore their application in deep ultraviolet （DUV） detection. To this end

The spectral properties of the samples under DUV light excitation were systematically studied. The emission spectra under DUV excitation and the linear response between the spectral intensity （peak and integral） and the laser excitation conditions （repetition frequency

single-pulse energy

and excitation spot size） were analyzed. The experimental results revealed that the samples exhibited narrowband （FWHM=45 nm） fluorescence emission at a peak wavelength of 541 nm under DUV excitation. Furthermore

the linear correlation coefficients between the spectral intensity （peak and integral） and the laser excitation conditions （repetition frequency

single-pulse energy

and excitation spot size） all exceeded 0.97

indicating a strong proportional relationship between the fluorescence conversion signal intensity and the incident energy intensity. This demonstrates the promising application potential of Co²⁺:YAG transparent ceramics in DUV detection.
