摘要：
It is reported the white light emission from a hybrid polymer light emitting diode (HyPLED) which has a film of YAG:Ce3+ nanoparticles. This white light is produced due to the combination of the blue light generated from a PLED and the green-yellow light coming from YAG:Ce3+ nanoparticles. This white light has CIE (International Commission on Illumination) coordinates of (0.31, 0.35) which is near of the ideal coordinate of (0.33, 0.33). The hybrid device presents a turn on voltage of 4V, as well as a maximum luminance and efficiency of 266cdm(-2) and 0.34cdA(-1) (at 9V), respectively. Finally, it was possible to tune the color emission from green to bluish-white by changing the operation voltage.
