的5d4f特征跃迁发射。荧光树脂片中荧光粉含量越高

样品发射强度越大

是一种适合用于白光LED封装的新型荧光材料。

Abstract

PC/YAG:Ce fluorescent resin pieces were prepared by using the methods of compound-melting and high-temperature molding. The transmittance of the YAG:Ce/PC fluorescent resin in 500~800 nm reaches approximately 65% (0.87 mm thick

double sides polished). The fluorescent resin was characterized by XRD

SEM and PL. The X-ray diffraction (XRD) patterns indicate that the fluorescent resin was pure Y

phase. The scanning electron microscopy (SEM) images show that YAG phosphor is distributed evenly in the fluorescent resin. The excitation spectra had a weak peak at 342 nm and a strong band at 448 nm. The broad emission peaks at about 532 nm can be attributed to 5d4f transition of Ce

ions. The higher the content of fluorescent powder is

the stronger the luminesence intensity of the samples will be. All results show that YAG:Ce/PC fluorescent resin may be a promising fluorescent material for white LEDs.
