Synthesis and characterization of photoluminescent cerium-doped yttrium aluminum garnet

Effects of local structure of Ce3+ ions on luminescent properties of Y3Al5O12:Ce nanoparticles

“…The positions of the diffraction peaks for the six samples are similar and consistent with the standard cubic structure of Y 3 Al 5 O 12 (JCPDS: 33–0040) and space group Ia-3d (230)29. It implies that the pure YAG phase can be successfully obtained at a temperature as low as 830 °C and no other crystalline phases such as Y 4 Al 12 O 9 (YAM) or YAlO 3 (YAP) form.…”

Energy transfer and enhanced 1532 nm emission in Er3+ and Ce3+ co-doped Y3Al5O12 nano-particles

“…Therefore, reactants are expected to be mixed more homogenous than the conventional polymer-assisted solegel method, where polymer is used as starting material. It is found the pure garnet crystalline is obtained at the temperature as low as 800 C, which is lower than the reported values as 900 or above 1000 C for YAG [11,14,15]. The luminescence properties of the codoped phosphors have been investigated as well.…”

Observation of green emission from Ce3+-doped gadolinium oxide nanoparticles

“…Through comparison with the excitation spectra of PEG-COOH and PEG-COOH coated Gd 2 O 3 nanoparticles, it is clear that the shoulder at 352 nm is from the PEG-COOH stabilizer, and the main peak at 378 nm originates from Gd 2 O 3 :Ce nanoparticles. The Ce 3 + _ dopant represents one possible origin of the 500 nm emission as it is similar to the green emission from YAG:Ce 3 + nanoparticles [9]. To identify whether it is from Ce 3 + , we measured the luminescence lifetime of the 500 nm emission.…”

“…Currently, Ce 3+ doped scintillators meet most of the requirements and are popular scintillators for radiation detection [3,4,6,7]. However, most Ce 3+ -doped scintillators reported have emissions in the UV-blue range except for Ce 3+ -doped yttrium aluminum garnet (YAG:Ce 3+ ), which has green emission [8,9].…”
