To study the H/He co-irradiation induced structural change of lithium silicate as tritium breeder,Li4SiO4 film was prepared by sol-gel method,and KeV H/He co-irradiation experiments of Li4SiO4 with different ion influences were carried out under room temperature.The structural change of irradiated samples was characterized by TEM,FTIR,RAMAN and GIXRD techniques.The results suggest the water content,acid content and the adding sequence of the metal precursors have influence on the crystalline phase of the dense Li4SiO4 films.Concerning H/He co-implanted samples,it was found that after implantation,H and He ions stayed at interstitial sites of the host lattice,thus the significant lattice swelling occurs,the lattice parameter increases with the ion influence.
