摘      要：Research on white light-emitting diodes（LEDs） based on multi-color-emitting quantum dots（QDs） is carried out in this *** equations of luminous efficiency（LE）,color rendering index（CRI）,chromaticity coordinates（x,y）,and color temperature（Tc） of white LEDs are obtained,according to the spectral-LE function Φof LED chips and *** calculated results indicate that the values of the performance parameters of QD-based white LEDs are closely related and proportional to the QDs＇ fluorescence spectra,and white LEDs with a high LE and a high CRI may be fabricated based on *** have provided theoretical guidance for preparing such white LEDs.
