Energy diagram of the increase of the band gap in the transition from bulk semiconductor to semiconductor nanoparticles. ВЗ - valence band ЗЗ - forbidden zone, ЗП - conduction band, the ВЗМО - upper filled molecular orbitals, НСМО - lower unoccupied molecular orbitals. б - The absorption spectra of CdS nanoparticles in the UV and visible wavelength range. Blue shift of the absorption edge is observed with a decrease in the size of the colloidal nanoparticles.
