Numerical Simulation of The Spectroscopic Properties of The Laser Dye for Low Concentrations

In the current study, a mathematical model using MATLAB program was studied depending on logistic power peak function to simulate change in absorbance with different values of concentrations Rhodamine B. There are five parameters that have been applied concentration this laser dye proposed by seventh degree. To measure absorption measurements, range from 4.7x10-7 3.76x10-6 M prepared B and dissolved deionized water at 556 nm. A JASCO V-630 spectrophotometer used record spectra dye. The intensity is detected silicon photodiode (S1337). results were found suggested approved relationship between significant accuracy high correlation coefficients approximated original data which determined more than 99.2%. advantages represent providing parameters, describe processes high-resolution property profiles.
