GLASS SUBSTRATE MANUFACTURING METHOD AND GLASS THEREOF

摘要

A glass of the present invention includes a first layer having a porous structure of nanoscale pores which are etched by an etchant that is a substitute for hydrofluoric acid (HF) or fluoride such that HF or fluoride is not used as the etchant, and a second layer which is not etched by the etchant. The glass is effectively applied to various applications requiring high light transmission such as a protective filter for a display device, a solar cell, a mobile communication device, glass of a building structure, and an optical element lens.

主权项

1. A glass comprising:
a first glass layer having a porous structure of nanoscale pores in a thickness direction of the glass, the first glass layer being formed by etching a surface of the glass with an alkali solution etchant, and the etchant being a substitute for hydrofluoric acid (HF) or fluoride such that HF or fluoride is not used as the etchant, and a second glass layer which is not etched by the etchant, wherein the porous structure is formed only by cleaning the surface of the glass and etching the cleaned surface of the glass with the alkali solution etchant, the etching not requiring any other addition processes, and wherein the porous structure is formed on the cleaned surface of the glass without forming a separate coating layer on the surface of the glass.
