摘要	By implantating high energy Zn ion into CaF2 matrix, the concentration of the implanted ions has a Gaussian's distribution below the surface of the CaF2, and ZnO quantum dots can be obtained by thermal annealing. Based on the theory of quantum chemistry, using Materials Studio and Gaussian 98 W programs, the electronic structure and optical properties of ZnO nanoparticles on GaF2 matrix were analysized. Selecting four of super-cells from the basal cells of ZnO, the absorption spectra of ZnO were calculated, and the result corresponds to the experimental one. The investigation of electionic structure of ZnO shows that the interaction of ZnO with GaF2 matrix is mainly from the interaction of 0 atom on ZnO surface with Ca, this interaction leads to the narrow of Fermi energy level and decrease of energy gap. The change of the structure of ZnO surface did not affect the diagnostic absorption spectra, the theoretical results are the. same as the experimental ones.
