PREPARATION AND CHARACTERIZATION OF SELECTIVE ABSORBANCE BIS (4-DIMETHYL AMINO DITHIO BENZIL) COMPLEX DYES COATINGS TO REFLECT LASER RADIATION THAT IN SURGERY ROOMS

Abstract

The Preparation dithio benzil dyes with high selective absorbance of Nd+3:YAG and Nd+3:glass laser Emission Spectrum and complexes were investigated and characterization by Fourier Transform Infrared (FT-IR ) spectrum and visble near Infrared spectrum (Vis-NIR) where stronger absorption peak showed a gentle alignment of the emission of lasers. After that adding these dyes to adhesive polymer to coat walls of surgery rooms and glasses to absorb the emissive rays of these lasers that effect on worker bodies .The importance of this research is ensure the safety of workers in the surgery rooms and appliance laser and reduce risk arising from interference radiation laser.
