Abstract
A method for manufacturing blue reflective glass substrates by ion implantation, the method including ionizing a N2 source gas so as to form a mixture of single charge and multicharge ions of N, forming a beam of single charge and multicharge ions of N by accelerating with an acceleration voltage A between 15 kV and 35 kV and a dosage D between −9.33×1015×A/kV+3.87×1017 ions/cm2 and 7.50×1017 ions/cm2. A blue reflective glass substrate including an area treated by ion implantation with a mixture of simple charge and multicharge ions according to the method.

A method for producing a blue reflective glass substrate, the method comprising:
- a) providing a N2 source gas,
- b) ionizing the N2 source gas so as to form a mixture of single charge ions and multicharge ions of N,
- c) accelerating the mixture of single charge ions and multicharge ions with an acceleration voltage so as to form a beam of single charge ions and multicharge ions of N, wherein the acceleration voltage A is comprised between 15 kV and 35 kV and the dosage D is comprised between −9.33×1015×A/kV+3.87×1017 ions/cm2 and 7.50×1017 ions/cm2,
- d) providing a glass substrate, and
- e) positioning the glass substrate in the trajectory of the beam of single charge and multicharge ions of N.
A method, comprising employing a mixture of single charge and multicharge ions of N to increase the blue color of the reflectance of a glass substrate, the mixture of single charge and multicharge ions being implanted in the glass substrate with an ion dosage and acceleration voltage effective to increase the blue color of the reflectance of the glass substrate.
