研究了掺铋锂铝硅酸盐玻璃的宽近红外发射。结果表明，玻璃的发射峰波长和宽度可以通过激发波长来控制。在900 nm激发下，发射光谱带宽最宽，超过500 nm。发射由两个高斯峰组成，峰处的受激发射截面计算为7.3x10（-21）和2.3x10（-20）cm（2）。在350 K以下，发光寿命几乎与温度无关，说明掺Bi锂铝硅酸盐玻璃的发光对热猝灭有很强的抵抗能力。(c)2006年，美国物理学会。
A broad near-infrared emission of Bi-doped lithium alumino silicate glasses has been investigated. It was found that the peak wavelength and width of the emission from the glasses could be controlled drastically by the excitation wavelength. The emission spectrum had the broadest bandwidth of more than 500 nm under 900 nm excitation. The emission consisted of two Gaussian peaks and the stimulated emission cross sections at the peaks were calculated as 7.3x10(-21) and 2.3x10(-20) cm(2). The lifetime was almost independent of temperature up to 350 K, indicating that the emission from the Bi-doped lithium alumino silicate glass has strong resistance to the thermal quenching.
