在SnO掺杂的含铋铝硼酸盐玻璃（CaO-B_2 O_3-Bi_2 O_3-Al_2 O_3-TiO_2）（CaBBAT）的近红外（NIR）区，观察到铋自由基物种与发射之间的强相关性。由于NIR发射的活化能类似于电子自旋共振信号的活化能，因此预期CaBBAT玻璃中的铋自由基物质是NIR发射的来源。通过与实验观测到的发射光谱和能量图的比较，证实了铋离子的低价态是近红外宽发射的来源。
A strong correlation between bismuth radical species and emission in the near infrared (NIR) region of SnO-doped bismuth-containing aluminoborate glass, (CaO–B2O3–Bi2O3–Al2O3–TiO2) (CaBBAT), was observed. Since the activation energy of the NIR emission was similar to that of electron spin resonance signal, it is expected that bismuth radical species in the CaBBAT glass is an origin of the NIR emission. Compared to the observed emission spectra with energy diagram of previous data, we have confirmed that bismuth ion possessing low valence is the origin of broad emission in the NIR region.
