Photochemical Method for Laser Absorption

Nanomaterials (Basel). 2022 Dec 9;12(24):4384. doi: 10.3390/nano12244384.

Abstract

During the laser application process, laser energy is usually converted into heat energy, causing high temperature, which affects the (high-speed) aircraft in routine flight. A completely novel photochemical method was investigated to potentially minimize the energy effect of the laser beam. Ag nanoparticles/C3N4 were synthesized by an ultra-low temperature reduced deposit method with Ag mean diameters of 5-25 nm for photofixation of N2. The absorption performance of laser can be improved by using appropriate charge density and small size Ag metal particles. The energy absorption rate was 7.1% over Ag/C3N4 (-40) at 5 mJ/cm2 of laser energy.
