The investigation of optical properties by doping halogen in the BaMoO4:Pr3+ phosphor system

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

“…Recently, the spectral properties of Pr 3+ -doped tungstate and molybdate crystals have attracted much attention [1][2][3][4][5][6]. 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.…”

Spectroscopic properties of Pr3+:Gd3Ga5O12 crystal

“…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. Also, two dominant transitions from the fluorescent 3 P 0 level of Pr 3+ to the lower 3 H 6 and 3 H 4 states can be mixed to give out white light for application to white LEDs [11].…”

Energy transfer and colorimetric properties of Eu3+/Dy3+ co-doped Gd2(MoO4)3 phosphors

“…Especially, rare earth doped phosphors have played an important role in realizing white LEDs. Up to now, many host materials such as molybdates [3,4], tungstates [5,6], vanadates [7,2] and aluminates [8,9], etc. were widely studied due to their long longevity, low cost, and excellent chemical and stabilities.…”
