The thin films of pyronin dyes doped with poly(vinyl sulphate) on glass substrate: Preparation and characterization

The thin films of pyronin dyes (PyB and PyY) with poly(vinyl sulfate) (PVS) are easily prepared from aqueous solution. The negatively charged PSV sheet leads it to quickly adsorb the dyes on it. The optical properties the thin films of the dyes with PVS can be easily tuned changing the amount of dyes and PVS.
