Synthesis and luminescent properties of nano-scale LuAG:RE3+ (Ce, Eu) phosphors prepared by co-precipitation method

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

“…This suggests that the Ce 3+ ions experience weaker crystal-field in the LuAG:Ce 3+ nano-garnet prepared by sol-gel technique than that of prepared by sol-gel combustion method. On the other hand, the energy splitting of the 5d state in LuAG:Ce 3+ is smaller than those in YAG:Ce 3+ [23]. Moreover, the emission peak (at 560 nm) of YAG:Ce 3+ nano-garnet [36] is redshifted compared to that of LuAG:Ce 3+ nano-garnet.…”

“…Zhong et al [22] synthesized Ce 3+ -doped LuAG garnets by sol-gel process and studied the influence of annealing temperature and active ion concentration on luminescent properties and defects. Wang et al [23] prepared Ce 3+ -doped YAG and LuAG nano-garnet powder by coprecipitation method and studied their photoluminescence spectra under VUV excitation. Potdevin et al [24] reported Ce 3+ -doped YAG and LuAG garnets by sol-gel route from alkoxide precursors and analysed their excitation and luminescence spectra.…”

Preparation, structure and photoluminescence of nanoscaled-Nd: Lu3Al5O12

“…The nanoscaled polycrystalline of LuAG has been successfully synthesized by co-precipitin method [13,14], so in this work the nano-crystalline Nd:LuAG was synthesized by this method. Nd2O3 (99.999%), Lu2O3 (99.999%), Al(NO3)3·9H2O (analytical purity), HNO3 (analytical purity) and NH3·H2O (analytical purity) were used as the starting materials.…”

Low temperature synthesis of monodispersed YAG:Eu crystallites by hydrothermal method

“…5 (a) exhibits the excitation spectra of the samples monitored at 590 nm using synchrotron radiation. The two broad bands in the spectra with the peaks at 173 and 230 nm are attributed to the fundamental absorption of YAG host and the charge transfer between Eu 3þ ÀO 2À , respectively [23,24]. the EXAFS results may also contribute to the enhanced luminescence intensity.…”
