Fig. 4: ML performance based on both the elasticity and triboelectricity of the polymer matrix at the ZnS:Cu single particle level.

From: Super elastic and negative triboelectric polymer matrix for high performance mechanoluminescent platforms

Fig. 4

FDTD simulation of the triboelectric field in the interfacial gap at 10 µm between ZnS:Cu and polymer matrix as a PDMS, b EF, and c DS, where the surface charge density is distributed over one-tenth of the total area (θ = 18°). d SEM image and e average dgap values between ZnS:Cu single particle and each polymer matrix under the strain of 60%. Error bars in e indicate 11% error. f ML images and g ML spectra of ZnS:Cu single particle depending on the polymer matrices, under the strain of 60%.
