摘　　要：最近,Ni^(2-)掺杂透明微晶玻璃得到了广泛关注。这种材料结合了晶体材料的高的发光量子效率和玻璃材料的优良的成纤特性,在980 nm激光激发下能在光通讯波段(1200～1700nm)产生超宽带荧光(荧光半高宽>200 nm),同时具有较长的荧光寿命(τ>200μs),有望成为宽带光纤放大器的增益介质。本文介绍了Ni^(2-)掺杂微晶玻璃材料的光学性质、微观结构和发光机理及其最近的研究进展,展望了这类发光材料的应用前景和今后的研究方向。Recently,transparent Ni^(2+)-doped glass-ceramics have received much attention.The luminescent materials combine the high quantum efficiencies of crystalline hosts with the relative ease of being drawn into fibers of glasses.They exhibit broadband emission (full width that half maximum>200 nm) in the near infrared wavelength region over the optical telecommunication range of 1200—1700 nm in the case of 980 nm excitation,and possess a long fluorescence lifetime (τ>200μs).These excellent properties make...
