摘要：

A two order of enhancement in near-infrared emission from Nd3+ in Ce3+/Nd3+ codoped yttrium aluminum garnet (YAG) matrix is obtained. This is due to efficient absorption by the allowed 4f-5d transition of Ce3+ ions then transfer to Nd3+ ions via a well matched energy level. This is among the most efficient near-infrared emission from Nd3+ ions strongly sensitized by exciting with an allowed transition in an inorganic matrix. This means that a new class of material, YAG:Ce,Nd, was produced and it potentially can be an efficient near-infrared phosphor that could be easily excited by a GaN light emitting diode, producing a new type of near-infrared emitter.
