The optical properties and laser characteristics of Cr3+ and Nd3+ co-doped Y3Al5O12 ceramics

Effective lattice stabilization of gadolinium aluminate garnet (GdAG) via Lu3+doping and development of highly efficient (Gd,Lu)AG:Eu3+red phosphors

“…Rare-earth aluminate garnets (REAG, RE 3 Al 5 O 12 ), especially YAG, have been widely studied for optical and high-temperature mechanical applications [1,2]. When properly activated with luminescent centers, the REAG compounds are important inorganic phosphors (such as YAG:Ce), which find applications in cathode ray tubes (CRTs), field emission displays (FEDs), vacuum fluorescent displays, scintillators, electroluminescent materials and so forth [3][4][5][6][7], owing to their high chemical and radiation stabilities, wide bandgap and excellent radiation conversion efficiency.…”

High transparency Cr,Nd:LuAG ceramics prepared with MgO additive

“…LuAG transparent ceramics possessing appropriate thermal expansion coefficients and thermal conductivity [9.6 W/(m·K)] are one type of potential host material in solar-pumped laser systems [7,8]. The two broad absorption bands ( 4 T 1 and 4 T 2 ) of Cr 3+ ions match the emission spectrum of solar light [9][10][11][12][13], and the energy absorbed by Cr 3+ can be effectively transferred to Nd 3+ , according to Refs. [2,[14][15][16].…”

Investigations of spin Hamiltonian parameters and local structures for three Cr(CN)63− centres in NaCl at three temperatures

“…Recently, considerable interest has been attracted in the study of alkali halides doped with transition-metal molecular ions. Cr 3+ belongs to 3d 3 transition-metal configuration, which demonstrates interesting luminescence [5] and laser performance [6] and applications in solar collectors [7]. Cyanide ion is an extremely useful bridging ligand in designing multimetallic complexes with interesting magnetic properties due to the strong exchange interactions between adjacent metal ions [8].…”

“…

The spin Hamiltonian parameters (g factors and zero-field splittings (ZFSs)) and local structures of three Cr(CN) 6 3-centres in NaCl are studied at three temperatures based on the perturbation calculations. The signs and magnitudes of the ZFSs D and E are in accordance with those of average bond length discrepancy

related to an ideal octahedron.
