Color Manipulation of Mechanoluminescence from Stress‐Activated Composite Films

Abstract

The prospective application of luminescence to imaging devices is shown using a combination of color-tunable and patternable mechanoluminescent materials. A white light source is demonstrated by using an alternative color tuning method, induced under high vibration conditions. As the implementation is fairly straightforward, it is expected that the present results will find a number of potential uses in current industrial applications.

Elastico-mechanoluminescence and crystal-structure relationships in persistent luminescent materials and II–VI semiconductor phosphors

“…[1][2][3][4][5][6][7][8][9][10]. Jeong et al [8][9][10] have demonstrated that the composite film containing ZnS:Cu, Mn and ZnS:Cu phosphors in a polydimethylsiloxane (PDMS) matrix can be used to produce light source, multicolour displays, and wind-driven light sources.…”

Background illumination enhanced photo-stimulated up-conversion emission in persistent luminescent SrAl2O4:(Eu2+, Dy3+)

“…Beside the persistent luminescence properties, LPLMs are reported to exhibit mechanoluminescence and photo-stimulated up-conversion (PSUC) properties [6][7][8][9][10][11].…”

Mechanoluminescence of (ZnS)1−x(MnTe)x nanophosphors excited by impact of a load

“…The widely studied elasticomechanoluminescent materials known to date are as follows [4][5][6]: show such an intense EML that it can be seen in daylight with naked eye. The elastico ML has potential for sensing [7,8], imaging [6,9], multicolour light sources and multicolour displays [10][11][12].…”
