Abstract
Research on white light-emitting diodes (LEDs) based on multi-color-emitting quantum dots (QDs) is carried out in this Letter. The 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 Φ of LED chips and QDs. The 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 QDs. We have provided theoretical guidance for preparing such white LEDs.
