摘要
<正>We reported effect of various alkaline oxides on the broadband infrared luminescence from bismuth-doped aluminophosphate glasses.The samples of (99-x)P2O5-17Al2O3-xR2O-1Bi2O3 (R=Li,Na and K, x=0 and 10 in mol%) were prepared under reducing condition controlled by additional carbon powders.The fluorescent intensity decreased with increasing content of alkaline oxides and basicity of host glasses.The 1/e fluorescence lifetime of the 72P2O5-17Al2O3-10R2O-1Bi2O3 (R=Li,Na and K) glasses decreased from 461 to 316μs,as alkaline ions changed from Li+ to K+.
