전계 및 기계적 발광필름 및 이의 제조 방법

Abstract

Provided is an electro-mechanoluminescent (EML) film. The EML film includes an upper supporting layer including an upper PDMS layer, including PDMS to which a stress is applied, and an upper electrode layer that is formed on a bottom of the upper PDMS layer and includes the PDMS and AgNW which are mixed with each other, a lower supporting layer including a lower PDMS layer and a lower electrode layer that is formed on a top of the lower PDMS layer and includes the PDMS and the AgNW mixed with each other, and an emitting layer formed between the upper electrode layer and the lower electrode layer, the emitting layer including a mixture, where a luminescent material with metal ions doped thereon is mixed with the PDMS, and simultaneously causing ML of a first color based on the stress and EL of a second color based on the electric field.
