Paper Abstract

The Nd3+ ions doped bulk glasses and thin films with the trimethylphosphate (TMP) as the precursor of P2O5 were prepared by the sol-gel technique. Their optical properties have been investigated. The Fourier Transform IR (FTIR) of Nd3+ doped SiO2-TiO2-P2O5 films have been measured to study the influence of P2O5 content in the removal of hydroxyl group. Fluorescence spectral results show stronger fluorescence intensity along with the narrowing of the emission bands due to the availability of the co-dopant P2O5 in the sol-gel glasses compared with those of aluminum co-doped glasses. Our experimental results show that up to 6wt percent of Nd2O3 could be incorporated into the P2O5-SiO2 glass matrix without significant fluorescence quenching effect due to the usage of the TMP as a precursor. We have also found that the hydroxyl groups could easily be removed at lower temperatures, as we increase the P2O5 content. It indicates that the P2O5 co-doping has a great potentiality in reducing the process temperature.
