Photon down-shifting by energy transfer from Sm3+ to Eu3+ ions in sol-gel SiO2-LaF3 nano-glass-ceramics for photovoltaics (Springer Link)

Abstract

95SiO2–5LaF3 sol-gel derived nano-glass-ceramics single doped with Eu3+ or
Sm3+ and codoped with both of them were successfully obtained. XRD
measurements confirm the precipitation of LaF3 nanocrystals after the
ceramming process, with mean size ranging from 10 to 20 nm which increases
with the thermal treatment temperature. The incorporation of rare-earth ions
into precipitated LaF3 nanocrystals was confirmed from luminescence spectra.
Intense yellow-red emissions were detected under UV and blue light excitation
in single and codoped samples. The effect of codoping with Eu3+ and Sm3+ ions
and the energy transfer mechanism between them have been analyzed in order to
increase the yellow-red emissions.
