One of the challenging tasks of the century is to clean up the contaminants of the environment by ecofriendly, sustainable and economically adoptable technologies. The application of quantum dots (QDs) is growing rapidly in to the field of nanotechnology. The electronic properties such as the energy of the highest occupied molecular orbital (EHOMO), the lowest unoccupied molecular orbital (ELUMO), the energy gap ΔE are correlated to the size of quantum dots (QDs) such as CdSe in the presence of different ligands. Linear regression equations were developed through statistical analysis using SPSS. In terms of correlation coefficient R2, both the size and nature of organic ligand capping affect the EHOMO, ELUMO and ΔE levels of QDs. Among all QDs, CdSe has the strongest correlation between its frontier molecular orbital energy levels with the QDs size. The R2 value is greater than 0.63 for a regression equation with a coefficient value of −0.17 and a constant of 2.9. This result implies that a unit decrease of size in the range lower than 7 nm would increase the band gap ΔE by 17%. Potential environmental applications of QDs are presented.
