Abstract With the methods of compound-melting and high-temperature molding, PC/YAG∶Ce fluorescent resin pieces were prepared. The transmittance of the prepared PC/YAG∶Ce fluorescent resin in 500～800 nm reaches approximately 65% (0.71 mm thick, double sides polished). The fluorescent resin was characterized by XRD, SEM and PL. The X-ray diffraction (XRD) patterns demonstrated that the fluorescent resin was pure Y3Al5O12 phase. The scanning electron microscopy (SEM) images showed that YAG phosphor was 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 5d→4f transition of Ce3+ ions. Decay curves for the fluorescence of PC/YAG∶Ce fluorescent resin show that the lifetime of the fluorescent resin was 61.5 ns. The luminous efficacy of the white LED packaged by the fluorescent resin and blue LED chip was 81.12 lm·W-1 at 100 mA. All results above of PC/YAG∶Ce fluorescent resin indicate a promising fluorescent material for white LEDs.
