Popis:	Near-infrared emission material, C e 3 + , E r 3 + co-doped C a 1.5 Y 1.5 A l 3.5 S i 1.5 O 12 has been synthesized via a high-temperature solid-state reaction method. The luminescence intensity of 1532 nm emission excited with 455 nm increases 4.2 times after the introduction of C e 3 + ions because of C e 3 + → E r 3 + radiation-reabsorption energy transfer and nonradiative energy transfer sensitization as well as the 4 I 11 / 2 ( E r 3 + ) + 2 F 5 / 2 ( C e 3 + ) → 4 I 13 / 2 ( E r 3 + ) + C e 3 + ( 2 F 7 / 2 ) cross relaxation between C e 3 + and E r 3 + ions. The result shows that the developed material is convenient to obtain high-efficiency, near-infrared emission using a commercial blue GaN LED as a pumping source.
