Luminescence properties of Tb3+:Y3Al5O12 nanocrystallites prepared by the sol–gel method

Sol–gel synthesis, characterization and study of substitution effects in different gallium-containing garnets

“…The most popular garnet is yttrium aluminium garnet (Y 3 Al 5 O 12 , YAG) which possesses good thermal, chemical stability and doped with transition metal or lanthanide ions could be employed as the host material for multi-coloured phosphors [11][12][13][14][15][16][17][18][19][20][21][22][23][24]. By selecting corresponding lanthanide ions may be produced red, green and blue (RGB) emission for use in tricolour white light [25][26][27].…”

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

“…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. YAG:Tb is a green phosphor used in FEDs [8][9][10][11], while Ce 3+ -activated YAG and LuAG yellow phosphors combined with blue light-emitting diodes (LEDs) are efficient white-light sources [12][13][14][15][16]. Eu-activated YAG and LuAG are also promising red phosphors that may be widely used in optical displays and lighting [16][17][18][19][20].…”

“…Therefore, soft chemical processing is currently widely adopted for the synthesis of fluorescent powders [7][8][9][10][11][12][13][14][15]. In this work, (Gd,Lu)AG:Eu phosphors were calcined from their precursors synthesized via carbonate coprecipitation with ammonium hydrogen carbonate as the precipitant [29].…”

Thermoluminescence and other optical studies on RbBr:Tb3+ crystals

“…Optical absorption, photoluminescence and thermoluminescence studies have been carried out on CsCldoped crystals with terbium [9], but no work could be traced on Tb-doped alkali halides with the fcc structure. The understanding of Tb 3+ in inorganic compounds is of great importance due to the potential technological applications as functional photonic materials, such as optical fiber amplifiers, lasing medium and frequency-converting devices [10][11][12]. Terbium ions can be widely used as luminescent centers in a number of applications due to their strong green emission, corresponding to the…”
