%X Influences of alkaline earth oxides on super broadband near infrared luminescence properties from Bi-doped RO-Al2O3-SiO2 （R = Ca,Sr,Ba） aluminosilicate glasses are investigated.The results show that under different pumping sources,the near infrared （NIK） luminescence shows different behaviors.Under 808 nm excitation,the infrared emission located at 1300 nm with lifetime more than 600μs is observed,whose intensity increases with the increase of ionic radius.However,under 690 nm excitation,the luminescence at 1100 nm with a full width at half maximum of 400 nm decreases with the increase of ionic radius.According to the above results,it is suggested that infrared emissions may originate from Bi+ and BiO.
