Abstract: A transparent top electrode composite film for organic optoelectronic devices includes a substrate, an MoOx film layer coated on the substrate, a doped Ag-based film layer coated on the MoOx film layer and an HfOx film layer coated on the doped Ag-based film layer. A preparation method of the transparent top electrode composite film, which is achieved under vacuum and low temperature, includes steps of (A) depositing an MoOx film layer on a substrate through thermal evaporation process or electron beam evaporation process without heating the substrate; (B) depositing a doped Ag-based film layer on the MoOx film layer through sputtering process or evaporation process; and (C) depositing an HfOx film layer on the doped Ag-based film layer through reactive sputtering process, thereby obtaining the transparent top electrode composite film. The composite film is able to be used as a top electrode material for organic optoelectronic devices.

Abstract: The present invention provides LED flickering shoes, which typically include a battery cell, a switch, a control circuit, a set of LED illuminators and cords, wherein said LED illuminators are mounted on the instep of the shoes body. Said LED flickering shoes gives out better flashing effect.

Abstract: The present invention provides a vibro-switch for flickering shoes, which typically includes a plastic shell comprising of a hood and a hood pad enclosing a cylindrical cavity; disk cooper sheet attached with a piezoelectric ceramics chip on the bottom side is suspended in the cylindrical cavity of said closed hood and hood pad so that the both sides of the stuck cooper sheet and the piezoelectric ceramics chip are kept certain space to the shell; a metal ball is put on top surface of the cooper sheet so as to roll freely; two cords, among of them, one is connected to the cooper sheet from the bottom side and led out the shell, the another is connected to the piezoelectric ceramics chip from the bottom side and stretched out of the shell. The present invent provides a vibro-switch for flickering shoes having simple structure, high reliability, easy manufacturing with lower production cost features.
