Abstract

Abstract: B-Phycoerythrin was an novel bio-photoelectronic material.Multilayer films formed of PDAA and B-PE were prepared by electrostatic self-assembly method.Visible absorption spectrum and fluorescent spectrum of the multilayer films were studied.The result showed the maximum absorption peak occurred red shift from 545 nm to 553 nm,and a delayed fluorescence peak at 573 nm was observed,the maximum absorption and photoluminescence intensity increases in proportion to the assembled layers.With the increase of the self-assembly layers,Obvious aggregate of B-PE was observed on the film by Inverted Microscope Eclipse.

Key words: B-Phycoerythrin, spectrum characteristic, thin film, electrostatic self-assembly
