研究了3d过渡元素在熔融石英中的光吸收。通过气相水解技术制备了一系列掺杂有0.01至0.1重量%的每种过渡元素（V至Cu）的高质量二氧化硅玻璃。测量了它们的光谱，计算了它们在200 ~ 2000 nm之间的实际吸收系数。在建议的波导使用范围内（λ 850 nm），V和Cr的吸收最多（apract= 2.6和1.2 dB/km ppbw−1（金属）），而Cu的吸收最少（apract = 1.0）。与传统玻璃的数据进行比较。
The optical absorption of 3d transition elements in fused silica was studied. A series of high‐quality silica glasses doped with 0.01 to 0.1 wt% of each transition element (V through Cu) was prepared by a vapor hydrolysis technique. Their optical spectra were measured, and their practical absorptivities were calculated between 200 and 2000 nm. In the proposed waveguide use range (∼ 850 nm), V and Cr appear to absorb most (apract= 2.6 and 1.2 dB/km ppbw−1(metal), respectively) and Cu the least (apract≃0). Comparisons are made with data for conventional glasses.
