Photoluminescence properties of Ca9Y(VO4)7 and Ca9Y0.95Ln0.05(VO4)7 (Ln3+= Eu3+, Sm3+, Pr3+)

Luminescence properties of Ca10K(PO4)7:RE3+ (RE=Ce, Tb, Dy, Tm and Sm) under vacuum ultraviolet excitation

“…The emission spectrum demonstrates the typical emissions of Sm 3+ , and the predominant emission peak is located at 601 nm ascribed to the 4 G 5/2 -6 H 7/2 transition. The other three relatively weak peaks at 563, 648 and 707 nm are attributed to the 4 G 5/2 -6 H 5/2 , 4 G 5/2 -6 H 9/2 and 4 G 5/2 -6 H 11/2 , respectively [25].…”

Synthesis and spectral property of Pr3+-doped tungstate deep red phosphors

“…In these crystals, Pr 3+ ions can be excited by blue light through the transitions from ground state to the 3 P J (J = 0, 1, 2) and 1 I 6 multiplets. Then the 3 P 0 → 3 F 2 transition provides remarkable deep red emission around 650 nm, which is hardly observed in other Pr 3+ -doped materials, such as the titanate, orthovanadate, niobate, and YAG [7][8][9][10][11][12][13][14]. This phenomenon has been discussed partly in Refs.…”

Spectroscopic properties of Pr3+:Gd3Ga5O12 crystal

“…It demonstrates a wide and complex emission spectra extending from ultraviolet (UV) to mid-infrared (MIR) regions. Recently the spectroscopic properties of Pr 3+ ion have been investigated extensively in various hosts including single crystals [1][2][3], nanocrystals [4], powders [5][6][7][8], glasses [9], etc. When the Pr 3+ ions are pumped to the closely grouped 3 P J (J = 0, 1, 2) multiplets, several emissions in red ( 3 P 0 → 3 F 2 ), deep red ( 3 P 0 → 3 F 4 ), orange ( 3 P 0 → 3 H 6 ), green ( 3 P 1 → 3 H 5 ), and blue ( 3 P 0 → 3 H 4 ) spectral regions have been demonstrated in tungstate [6], vanadate phosphors [8], molybdate [3], fluoride crystals [1,10], etc.…”
