A Study on Optical Absorption Spectra of Photochromic Dye Using Mixed-Level Factorial Design

The photochemical transformation of the organic photochromic dyes is influenced by many independent factors. One of the most important characteristics of the photochromic dyes that need to be focused on is its photostability. The effects of the type of dyes and solvents on the optical absorption spe...
