Abstract Potassium bromide crystals were effectively colored electrolytically with a lab-made electrolytic apparatus at 693 K by applying a DC 1 200 V voltage.A lot of F, R, M and N type and some new unknown color centers were produced in the colored potassium bromide crystals, and the formation and transformation mechanisms of the color centers were presented.Spectral measurement and analysis were carried out systematically for the colored crystals, the spectral bands of corresponding color centers were reasonably resolved from the measured spectra, and the corresponding spectral parameters of the spectral bands were accurately determined by using spectral decomposition.
