Sol–gel preparation and photoluminescence properties of Ce3+-activated Y3Al5O12 nano-sized powders

Nanomaterial Host Bands Effect on the Photoluminescence Properties of Ce‐Doped YAG Nanophosphor Synthesized by Sol‐Gel Method

“…In fact, this effect can be explained by the improvement of the degree of crystallinity and decrease of surface defects as a function of heat treatment temperature. Similar results have been previously reported by Fadlalla and Tang [5]. Indeed, annealing sample may improve the substitution of Ce 3+ ions into Y lattice in the YAG matrix with good incorporation of Ce 3+ ions that can contribute to the enhancement of emission intensity [6,35].…”

“…The YAG structure can be easily doped with several rare earth ions, allowing emissions of wavelengths from the near-infrared to ultra violet. Trivalent cerium doped YAG (YAG:Ce) is extensively utilized for numerous applications, such as cathode-ray tubes [3], field emission displays [4], scintillations, and electroluminescent displays [5]. The most important application of the YAG:Ce powder is converting the blue light emitting diodes (LEDs) radiation into a very broad band yellow emission, which can be used as one of the most common methods for producing white light with a gallium nitridebased blue LED [6,7].…”

Sol–gel synthesis and thermal stability of luminescence of Lu3Al5O12:Ce3+ nano-garnet

“…Such applications depend on the luminescent properties of rare earth ions, e.g., sharp lines, high efficiency and high lumen equivalence [3]. Recently, the WLEDs composed of blue LED and a yellow YAG:Ce 3+ nano-garnet have been investigated extensively due to their wide applications, such as back lighting for liquid-crystal displays and incandescent lamps [4][5][6][7][8][9][10][11]. These applications are particularly useful for saving electric power owing to the lower-energy consumption of LEDs.…”

Comparative study on photoluminescence of amorphous and nano-crystalline YAG:Tb phosphors prepared by a combustion method

“…Ce-doped YAG emits yellow light that complements blue light emitted by single-crystal GaN to generate white light [7,8]. Eu-activated YAG is a promising red phosphor widely used in optical display and lighting applications [9,10].…”
