Preparation and Application of ZnS∶Cu-based Liquid Bridged ACEL Fiber Device

Abstract With the rapid development of electronic devices and the demand for flexible wearable display devices it is urgent to develop a flexible electroluminescent fiber device.In this paper a ZnSCu-based liquid bridged ACEL fi ber device was prepared by the method of conjugate electrospinning.The test results show that the device has good me chanical properties and electroluminescence properties.The effects of electrospinning layer number and voltage on the luminescence properties of fibers were investigated.With the increase of spinning layer number the luminescence in tensity of fibers increased first and then decreased and the electroluminescence performance was the best when the number of layers was 3.With the increase of the driving voltage the luminance of the fiber gradually increases and the luminance of the luminous fiber can reach 192. 5 cdm -2 under the driving condition of 3. 77 Vm -1 and 10 kHz.The electroluminescent fibers prepared in this work can effectively distinguish different liquid electrodes and have the
