Through XRD spectra, DTA-TG and photo-luminescent analysis, the possible reaction path and the emission mechanism of the phosphor were mentioned, and the partial Judd–Ofelt parameters and quantum efficiency of ${hbox{Eu}}^{3+} ^{5}{hbox{D}}_{0}$ energy level were calculated under 395 nm excitation. The results indicate that the red-emitting phosphor, of which the quantum efficiency is 13.43%, can become the potential applications for white light-emitting diode in the future.]]> 8 3 127 131 177 8 3 132 137 954 8 3 138 144 1444 $({R}^{2} =0.945)$ .]]> 8 3 145 153 2057 $times$ 32 LEDs. Resulting time diagrams and frequency responses are presented. The results indicate that, despite expected significant advantage of binary PWM methods, in realistic case all methods' performance is similar.]]> 8 3 162 165 474
