| Abstract: | Ultra light cross linking films of ether type polyurethane doped with Eu 3 were prepared.The effects of the cross linking time and Eu 3 concentration on the fluorescence properties were investigated,the film fluorescence intensity increased at first and then decreased.The scanning electron microscope observations show that the film was homogeneous.The thermal properties were also investigated. |
