Enhancing the efficiency of solar cells via quantum dots (QDs) as an energy-down-shift (EDS) layer is a new approach to utilize the wasted energy in the ultra-violet (UV)-light, but the smaller Stokes shift in QDs leads towards partial self-re-absorp

Quantum dot enhancement film (QDEF) working in tandem with a blue light-emitting-diode (LED) back-light-unit (BLU) has been recently used in liquid crystal display (LCD) to minimize the cross talks between the polarized emitting B-, G-, and R-light.
