Light scattering glass material modified by the surface ion exchange for the energy efficient using in the technical and decorative lighting

The research data related to glass surface treatment and new scattering glass material manufacture by the surface modification with the use of the surface ion exchange are given. The special features of the optical properties of the modified soda lime silica glass with/without the thin Au layer are described and compared with that data related to chemical etched glass. The glass modified by surface ion exchange is characterized by more effective simultaneous light transmission and light scattering and by more strongly pronounced spectral and angular dependences of the scattered light. It was found the noticeably greater (up to 16 times) light intensity at light propagating in the full internal reflection regime. Presented optical data may be useful in the technical and decorative illuminating engineering
