【摘要】 掺铊的氯化钾单晶;经X射线辐照和光转型后,获得F_A(Ⅲ)心在77K时,该色心的荧光谱带自1.3至1.7μm,峰位为1.5μm,其激发光谱带自0.9至1.2μm,峰位在1μm附近.F_A(Ⅲ)心的室温光热稳定性,在开始的数天略有衰减,其后趋于平衡,成为稳定的F_A(Ⅲ)心.更多还原

【Abstract】 The FA(III)centers have been obtained by X-ray irradiation and light conversion in T1+:KC1 single crystals, its emmission band and excitation band lies from 1.3 to 1.7m and 0.9 to 1.2m with peaks at 1.5m and 1m respectively (77K). The light and thermal stability (R.T)of FA(III)centers decreases slowly in the first few days, and then remains unchanged, the stable FA(III)centers can be finally obtained.更多还原
