The invention relates to the technical field of glass cover plates, and provides a glass cover plate, a preparation method of the glass cover plate and electronic equipment, the glass cover plate is prepared from photosensitive glass, photosensitive metal ions in the glass cover plate can be reduced into photosensitive metal atoms, and the photosensitive metal atoms can be reduced into photosensitive metal atoms. The photosensitive metal atoms gather in the photosensitive glass to form the photosensitive metal colloid particles with different concentrations, the photosensitive metal colloid particles have certain sizes, and the photosensitive metal colloid particles with certain sizes and different concentrations present different colors, so that the glass cover plate can present colorful colors, and the service life of the glass cover plate is prolonged. And the photosensitive metal colloid particles are formed in the glass cover plate, so that the influence of the external environment can be isolated, and the color on the glass cover plate is more stable and durable.

A photosensitive glass, a method for preparing the same, a strengthened photosensitive glass, and a use thereof, by controlling a raw material composition of the photosensitive glass, not only can ensure the stability of the glass composition during melting of the photosensitive glass containing Ag2O, but also can solve the problem of silver atom Ag 0 The problem of loss and damage of noble metal containers, and also can ensure that the optical transmittance of the exposed region of the photosensitive glass in the visible light and near-infrared wavelength range is extremely low after radiation treatment and heat treatment, and the shielding of the optical signal can be realized.
