Luminescence excitation spectra of active centers in bismuth-doped vitreous SiO(2) and vitreous GeO(2) optical fibers under the two-step excitation have been obtained for the first time. The results revealed only one bismuth-related IR active center formed in each of these fibers. The observed IR luminescence bands at 1430 nm (1650 nm) and 830 nm (950 nm), yellow-orange (red) band at 580 nm (655 nm), violet (blue) band at 420 nm (480 nm) belong to this bismuth-related active center in the vitreous SiO(2) (vitreous GeO(2)), correspondingly.
首次获得了铋掺杂的二氧化硅玻璃光纤和二氧化锗玻璃光纤中活性中心在两步激发下的发光激发光谱。结果表明，在这些光纤中每一种都仅形成了一个与铋相关的红外活性中心。在1430nm（1650nm）和830nm（950nm）处观察到的红外发光带、在580nm（655nm）处的黄橙色（红色）带、在420nm（480nm）处的紫色（蓝色）带分别对应于二氧化硅玻璃（二氧化锗玻璃）中这个与铋相关的活性中心。
