Abstract

The invention relates to a preparation method of laser blinding protective lenses, and belongs to the technical field of functional materials. Graphene-like two-dimensional material molybdenum disulfide nanosheets are used as basal bodies; as the basal bodies have the advantages of high plane internal carrier mobility, small indirect band gap, high fluorescence quantum yield, large surface area, excellent photoelectric chemical stability and the like, ternary quantum dots are synthesized in layer gaps thereof; through a barrier effect of molybdenum disulfide and a synergistic effect with the quantum dots, nonlinear optical amplitude limiting materials with excellent dispersibility, high stability and difficult deterioration are obtained; and through a surface effect of a quantum effect, aquantum size effect, a quantum confinement effect, a macroscopic quantum tunneling effect and the like, increment of polarizability and increment of absorption coefficients are shown, higher nonlinearoptical parameters are achieved, and reliable and effective protecting methods can be provided to laser operators.

Description

technical field [0001] The invention relates to a preparation method of laser blinding protective lenses, which belongs to the technical field of functional materials. Background technique [0002] Laser has the advantages of strong directionality, monochromaticity and good coherence, and has been widely used in military, medical and industrial fields. Laser protection materials have become a matter of great concern in the military and civilian fields. Divided from the principle of protection, the laser protection materials and protection technologies currently used at home and abroad are mainly divided into two categories: linear and nonlinear laser protection. [0003] Linear protection is mainly divided into three types: absorption type, reflection type and absorption / reflection composite type. Absorbing protective materials are made by adding light-absorbing dyes to the polycarbonate base material. The advantage is that the protective effect has no angle dependence, b...
