"pulse-shaped light generates substantial concentrated energy at regular intervals, replacing heat treatment, saving time... absorb wide range of wavelengths, low processing costs (solution processing), excellent photoelectric properties... fewer surface defects so less charge recombination. performance deterioration... heat treatment exposing dots to light for few ms... extended traveling life of charges (electrons, holes), high efficiency... quantum dot process with excellent ripple effect... optoelectronic devices"
