The influence of weak irradiation on the aggregation stability of quantum dots is considered. It was shown that under combined UV and visible light irradiation, a gradual increase in spontaneous aggregation takes place, testifying decrease in stabilizing potential barrier height. Thereby, the laser-induced controllable self-assembly of CdTe QDs is recommended to be performed over a time period between 80 and 100 min after the beginning of low intensity irradiation under conditions equivalent to those applied in this study.
