La-Doped Alumina, Lanthanum Aluminate, Lanthanum Hexaaluminate, and Related Compounds: A Review Covering Synthesis, Structure, and Practical Importance

“…Among these, perovskites (e.g., YAlO 3 ) and MP-HAs (e.g., CaAl 12 O 19 , SrAl 12 O 19 , and LaMgAl 11 O 19 ) provide excellent host environments for Pr 3+ , which exhibit adequate phonon energies and a suitable crystal-field strengths of the O 2– environment. More details can be found in a recent review article by Tanaka et al …”

Enhanced thermally stable performance of Pr3+-doped vanadate phosphor by inhibiting the intervalence charge transfer quenching channel

“…[1][2][3][4][5][6][7][8][9][10][11][12][13] Pr 3+ is often doped with oxide crystals as an optical material because its energy level structure allows linear and nonlinear effects. [14][15][16] Moreover, due to the electron transfer between different metal ions, the trivalent Pr 3+ ion can undergo metal-to-metal charge transfer with transition metal ions (Mn + ), forming a low-location charge transfer state, i.e., intervalence charge transfer (IVCT). [17][18][19][20][21] The IVCT mechanism can affect the electron distribution of the 4f electronic group state of Pr 3+ , 22 leading to red emission from the 1 D 2 state by reducing the electron population of the 3 P 0 state.…”

Rare-earth and transition metal ion single-/co-doped double-perovskite tantalate phosphors: Validation of suitability for versatile applications

“…Moreover, Ln 3+ (e.g., Eu 3+ , Sm 3+ , and Pr 3+ ) and Mn 4+ single/co-doped phosphors have been applied in other fields including solar cells, drug delivery, field emission displays, lasers, anti-counterfeiting films, batteries, LIR thermometry, luminescence lifetime thermometry, and pressure-dependent manometry [18][19][20][21][22][23][24][25][26][27][28][29][30]. The Ca2InTaO6 (CITO) with the double-perovskite (A2BB'O6) structure provided highly distorted [InO6] octahedron for Ln 3+ and [TaO6] octahedron for Mn 4+ , which can lead to good luminescence performances.…”
