Structural and photoluminescence properties of UV-excited Er3+ doped Ba2CaWO6 yellowish-green phosphors

An Er3+ doped Ba2MgWO6 double perovskite: a phosphor for low-temperature thermometry

“…A similar observation has been reported previously. 15,54 It is difficult to observe without magnification of the region at 488, 530, and 822.2 nm as a consequence of very weak transitions from the 4 F 7/2 , 2 H 11/2 , and 4 I 9/2 , to 4 I 15/2 , respectively. For more details, the assignment of energy levels can be found in Table S1.…”

“…11 These materials, due to their rigid and highly symmetrical crystal structure, are interesting hosts for lanthanide ions. Such materials are studied as potential phosphors for up-conversion, 12 displays, 13 and luminescent thermometers. [14][15][16][17][18][19] In particular, barium magnesium tungstate with the formula Ba 2 MgWO 6 , abbreviated as BMW, has been studied extensively 18,[20][21][22][23][24][25][26][27][28][29] due to its high symmetry confirmed by the Goldschmidt tolerance factor (1) being very close to 1.…”

Strong Green Emission of Erbium(III)-Activated La2MgTiO6 Phosphors for Solid-State Lighting and Optical Temperature Sensors

“…Recently, E. Sreeja et al suggested yellowish-green Ba 2 CaWO 6 :Er 3+ phosphors for solid-state lighting. 12 K. Li et al demonstrated CsGd-(MoO 4 ) 2 :Yb 3+ /Er 3+ /Ho 3+ with tunable-luminescent properties for solid-state lighting and solar cells. 13 S. Som et al described NaYF 4 :Er 3+ /Yb 3+ phosphors for fingerprint detection, etc.…”

“…Erbium­(III) (Er 3+ ), as an important element in the RE family, has been widely investigated and applied in lots of fields as a result of its unique optical properties. Recently, E. Sreeja et al suggested yellowish-green Ba 2 CaWO 6 :Er 3+ phosphors for solid-state lighting . K. Li et al demonstrated CsGd­(MoO 4 ) 2 :Yb 3+ /Er 3+ /Ho 3+ with tunable-luminescent properties for solid-state lighting and solar cells .…”

Effect of Ceramic Formation on the Emission of Eu3+ and Nd3+ Ions in Double Perovskites

“…Double perovskites materials, i.e., A 2 BB’O 6 , have recently been receiving more and more attention from scientists due to their fascinating physical and chemical properties stemming from their flexible structural modification ability. As a result, double perovskites found a wide range of applications in white light-emitting phosphors [ 1 , 2 ], transparent and translucent ceramics [ 3 , 4 , 5 , 6 ], dielectric materials [ 4 , 7 , 8 ], optical thermometers [ 9 , 10 , 11 ], scintillators [ 12 ], etc. Among them, scintillators are widely used in medical diagnosis, computed tomography, non-destructive inspections, security, nuclear radiation detection, etc.…”
