Luminescence of GdF3:Pr:Yb and YF3:Pr:Yb Solid Solutions Synthesized by Crystallization from the Melt

Spectral and luminescence characteristics of GdF 3 :Pr:Yb and YF 3 :Pr:Yb solid solutions synthesized by crystallization from the melt were investigated. Down-conversion luminescence of Yb 3+ in the region of 2 F 5/2 → 2 F 7/2 transitions with 445-nm excitation was studied. The energy-transfer coeff...

Zusammenfassung:Spectral and luminescence characteristics of GdF 3 :Pr:Yb and YF 3 :Pr:Yb solid solutions synthesized by crystallization from the melt were investigated. Down-conversion luminescence of Yb 3+ in the region of 2 F 5/2 → 2 F 7/2 transitions with 445-nm excitation was studied. The energy-transfer coefficient from Pr 3+ to Yb 3+ was
