Contrastive Research of the Y3Al5O12: Ce3+ Yellow Phosphors Prepared by Different Methods.

Ce3+ doped Y3Al5O12 : Ce3+ yellow phosphors are prepared by the high-temperature solid-state method, sol-gel method and hydrothermal-pyrolysis methods. The influences of the preparation methods on the phase, morphology and photoluminescence properties of the YAG : Ce3+ yellow phosphors are investigated by XRD, FESEM and PL, respectively. The results indicate that the three methods all realize the substitution of Ce3+ ions for Y3+ ions, and that the cubic crystalline structure of the Ce(3+)-doped YAG phosphors is unchanged.

[Preparation and photoluminescent property of sphere Y2.96Al5O12 0.04Ce3+ phosphor for white light-emitting diodes].

Cesium ions doped yttrium aluminum garnet (Y2.96Al5O12 : 0.04Ce3+) phosphors for white light emitting diodes (WLED) were successfully prepared by hydrothermal-thermolysis method.
