Abstract
PbCl2-quantum dots formed within NaCl-matrice have been monitored in details using optical spectroscopy. Within context of nucleation theory and utilizing the evolution of absorption curves at various temperatures, surface energy between newly-formed QD and matrice (ÏÂ â
 0.06 Jmâ2), resp. activation energy of diffusion of divalent lead ions in NaCl-matrice (EA â
 0.4 eV) have been determinated. These quantities are in very good agreement with those obtained for other alkali chlorides and may serve to optimize preparation of QD within bulk solid.
