ELECTROLUMINESCENCE MATERIAL FOR LED AND METHOD FOR IMPROVEMENT OF LUMINOUS EFFICIENCY

摘要

An electroluminescence material for LEDs is provided to ensure an excellent luminous efficiency by accomplishing energy transfer between organic polymer electroluminescence compounds on nanoagglomerates. An electroluminescence material for LEDs is a nanoagglomerate obtained by mixing 100 parts by weight of any one derivative selected from the group consisting of polysilole represented by the following formula 1, polygermole represented by the following formula 2, and silole-germole copolymers represented by the following formula 3, with 50-500 parts by weight of phenylmethylpolysilane represented by the following formula 4. In the formulae, R is any one selected from a methoxy group, an amine group, or a thiol group, and n is 1-100.
