Spectroscopic study of DCM as an active medium for luminescent solar concentrators

Cis and trans isomers have been studied in the solution of the dye DCM. The photophysical parameters of DCM dissolved in methylene chloride have been also studied as a function of concentration and the results demonstrate the unique nature of the photophysics of this laser dye and the great potential that it offers for use in a low cost luminescent solar concentrator.
