Resumo
This work aims to investigate the characteristics related to the luminescence spectra of borate glasses CaO-Al2O3-H3BO3 and CaO-Al2O3-H3BO3 doped respectively with 1.0 wt% of Yb3+ and Ce3+. These glasses were produced by melt and rapid cooling method. The compounds are from Sigma Aldrich with a 99.99% degree of purity. The spectral characteristics of Yb3+ and Ce3+ ions in borates and phosphates are important to optical applications. Such glasses can be useful as optical fibers doped and in solid-state lasers. The emission and excitation spectra were obtained using a spectrofluorometer (Nanolog-Horiba) with a photomultiplier tube R928P equipped with a Xenon lamp (CW 450 W) as the excitation source, and a filter of 399 nm. Lifetime was also obtained with the NanoLog using the same lamp and the same detector. Fig.1 (a) e (b) shows emission of Ce3+ (excitation 335 nm) and Yb3+ (excitation 334 nm) ions of borates glasses.
