Eu3+-doped bismuth borate based glasses with various contents of WO3 were fabricated by melt quenching. Optical properties of Eu3+ ions in these ternary systems and their dependence on the WO3 content were investigated: absorption and emission spectra were studied as the WO3 molar ratio was adjusted from 1 to 5 mol %. The Judd-Ofelt parameters were calculated from the emission spectra and expressed in terms of reduced matrix U t (t = 2, 4, 6) characters for optical transitions. The influence of WO3 content on the Judd-Ofelt intensity parameter ?2 was also investigated. Experimental results lead us to conclude that the optimum luminescence of Eu3+-doped bismuth borate based glasses is achieved if the WO3 content is 3 mol %.
