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 in particular relates to a near-infrared-proof sunglass using photonic crystal technology and a preparation method thereof. Background technique [0002] Solar radiation is divided into three regions according to wavelengths: ultraviolet, visible light, and infrared. Its energy is mainly concentrated in the near-infrared region, accounting for about 97%. Infrared rays belong to the category of electromagnetic waves and are radiation with strong thermal effects. The range of infrared rays is divided into near-infrared, mid-infrared, and far-infrared regions; the near-infrared region accounts for about 53% of the solar radiation reaching the ground. The infrared wavelength in general is a wavelength between 780nm and 4000000nm. Its wavelength is shorter than radio waves and longer than visible light. Infrared rays cannot be seen by the naked eye. Any object emits infrared rays. The infrared ...
