MECHANOLUMINESCENCE COLOUR-TUNABLE COMPLEX FILM AND METHOD FOR TUNING COLOUR THEREOF

摘要

Provided are a colour-tunable complex film which emits light in a mechanical manner and a method for tuning colour thereof. Modes of embodiment of the present invention comprise a mixture of at least two mechanoluminescence materials which emit light by applied mechanical energy and a stress transfer material which transfers mechanical energy applied from the outside to the mechanoluminescence materials, wherein among the at least two mechanoluminescence materials, a first emission spectrum of the first mechanoluminescence material is different from a second emission spectrum of the second mechanoluminescence material.
