Abstract

The invention provides a near infrared ray preventive sunglass lens via photonic crystal technology and a preparation method of the sunglass lens. A two-dimensional photonic crystal membrane is deposited in the front side of a lens substrate, and comprises indium tin oxide nano-columns grown on the surface of the lens substrate by crystallization, hafnium oxide nano-columns filled into gap areas of the indium tin oxide nano-columns and an indium tin oxide membrane positioned in the outer surface layer; and certain inclination angle is formed between the indium tin oxide nano-columns and the lens substrate. The two separated nanometer indium tin oxide layers are formed to realize higher near infrared ray blocking rate and high visible light transmittance. In the near infrared ray waveband, reflection is generated due to carrier absorption and plasma vibration, heat radiation of the near infrared ray waveband is blocked by both absorption and reflection, namely, the near infrared rays are shielded by both reflection and absorption, and light waves in the nearly infrared area are blocked.

Description

Technical field [0001] The invention belongs to the technical field of sunglasses, and particularly relates to a near-infrared-proof sunglasses lens with photonic crystal technology and a preparation method thereof. Background technique [0002] Solar radiation is divided into three regions: ultraviolet light, visible light, and infrared light according to wavelength. Its energy is mainly concentrated in the near-infrared light region, accounting for about 97%. Infrared light belongs to the category of electromagnetic waves, which is a kind of radiation with strong heat effect; people will use different wavelengths The range of infrared rays is divided into near infrared, mid-infrared, and far infrared regions; the near-infrared light region accounts for about 53% of the solar radiation reaching the ground. The general infrared wavelength is a wavelength between 780nm-4000000nm. Its wavelength is shorter than radio waves and longer than visible light. Infrared rays cannot be seen...
