Study of the photoluminescence properties of crystal phosphors SrTiO3:Pr3+ and SrTiO3:Pr3+, Al
Fine-grained powder crystal phosphors SrTiO3:Pr3+ and SrTiO3:Pr3+, Al have been investigated. Their photoexcitation, luminescence, and photoconductivity spectra have been recorded. It is found that only one center (PrSr ·) is responsible for the luminescence in SrTiO3:Pr3+, while the luminescence in...

| Summary: | Fine-grained powder crystal phosphors SrTiO3:Pr3+ and SrTiO3:Pr3+, Al have been investigated. Their photoexcitation, luminescence, and photoconductivity spectra have been recorded. It is found that only one center (PrSr ·) is responsible for the luminescence in SrTiO3:Pr3+, while the luminescence in SrTiO3:Pr3+, Al is due to two centers: (AlTi′ PrSr ·)× and PrSr ·. A mechanism of energy transfer upon luminescence excitation from the (AlTi′ PrSr ·)× center is proposed |
