The effect of gold nanoparticles on crystallization processes in photostructured lithium-silicate glass
The surface plasmon resonance of gold nanoparticles (NP) is investigated, allowing their sizes before and after X-ray irradiation to be determined. It is shown that X-ray irradiation results in the growth of NP, while their heat treatment results in their reduction. The quasi-atomic structure of gold NP is assumed, leading to the entrapment of electrons on unoccupied orbitals upon X-ray irradiation. An explanation of the crystallization and amorphization of photostructured glass in the lithium-silicate system is suggested based on the fact that gold NP are negatively charged.
