Luminescent polystyrene films, a novel way to reduce styrofoam residues

Polystyrene (PS) films doped with blue, yellow and red organic pigments have been deposited on glass and on commercial LED chips by spray pyrolysis using recycled PS as precursor, at deposition rates between 100 and 200 A° /s. Doped films have roughness between 100 and 2500 °A depending on the kind...
