Abstract
⺠Eu3+-doped SiO2-B2O3-PbO2 glasses had their optical properties investigated. ⺠AFM images show a precipitated nanocrystalline phase. ⺠The NCs size can be controlled by increasing heat treatment or by adding Eu3+ ions. ⺠Was observed a strong Eu3+ photoluminescence enhancement as a temperature increases. ⺠A thermal energy transfer model was proposed to explain the results.
