摘 要：<正>We report on a simple and novel method to induce Si-related oxygen-deficient defects in CaO-Al2O3-SiO2 glasses by using Al metal instead of part Al2O3.Blue emission is observed from the glass samples.Moreover,the quantities of the oxygen-deficient defects can be controlled by adjusting Al content. We also prepare glass samples using Al instead of part Al2O3 and doped with Eu3+ ions.Addition of Al results in reduction of Eu3+ ions to Eu2+ ions and change of the luminescence property.The investigation made on to control and characterize the defects could lead to the development of more efficient economical materials with improved properties.
