Abstract
A method of increasing photo-luminescent quantum yield (PLQY) of QDs to be used as down-converters placed directly on an LED chip includes synthesizing a plurality of quantum dots, applying energy to the plurality of quantum dots to increase PLQY of the plurality of quantum dots, dispensing the plurality of quantum dots onto the LED chip, and curing the LED chip.
