Abstract
The present invention relates to glass with a single reinforced layer, comprising a glass body and the single reinforced layer formed in a surface of the glass body. The compressive stress of the single reinforced layer trends to decrease non-linearly from the surface of the glass body to the interior of the glass body. The compressive stress curve of the single reinforced layer has an inflection point. The gradient of a first curve section in front of the inflection point is greater than the gradient of a second curve section behind the inflection point. The overall refractive index of the single reinforced layer trends to decrease non-linearly from the surface of the glass body to the interior of the glass body. The refractive index curve of the single reinforced layer has at least two inflection points. Furthermore, a method for preparing the glass with a single reinforced layer is provided.
