Influence of photoactivation on luminescent properties of colloidal InP@ZnS quantum dots

The use of photo- and thermoactivation during the liquid-phase synthesis of colloidal quantum dots was found to yield luminescing InP@ZnS quantum dots with a luminescence quantum yield close to unity. Activation mode was found to have little or no influence on the maximal luminescent efficiency but affect particle size distribution. Compared to thermal activation, photoactivation ensures the formation of more monodispersed particles.
