Abstract
It has been found that the luminescence quantum yield of CdSe colloidal quantum dots (QD) synthesized in the presence of n-octadecylphosphonic acid and trioctylphosphine oxide significantly depends on the polarity of the medium in which they are dispersed and increases with decreasing the polarity of the medium. Different methods of increasing the quantum yield have been studied; the conditions have been found under which its value reaches 0.9, which is comparable to record values currently known for core@shell QD and is maximum for QD without an additional semiconductor shell. The effect of precipitating solvents on the luminescence efficiency of QD has been studied.
