Luminescence of BaSiO3 crystals doped with Er3+ and Yb3

The Stokes and anti-Stokes luminescence of undoped and rare-earth-doped (Er 3+ and Yb 3+ ) BaSiO 3 has been studied in the temperature range 78–450 K under excitation at 10–1000 mV. The results indicate that the emission mechanism in BaSiO 3 crystals is hole recombination and that the anti-Stokes lu...

Summary:The Stokes and anti-Stokes luminescence of undoped and rare-earth-doped (Er 3+ and Yb 3+ ) BaSiO 3 has been studied in the temperature range 78–450 K under excitation at 10–1000 mV. The results indicate that the emission mechanism in BaSiO 3 crystals is hole recombination and that the anti-Stokes luminescence is due to consecutive sensitization; that is, the Yb 3+ ions in the BaSiO 3 compound act as luminescence sensitizers, and the Er 3+ ions, as activators.
