The effect of mechanical behavior on the performance of UVC ML. a Evolution of ML intensity over 10,000 stretching cycles, and b corresponding ML emission spectra over varied stretching cycles of the SBO:Pr/PDMS elastomer film under varying numbers of stretching cycles at different strain levels (40%, 60% and 80%, frequency: 5 HZ). c ML intensity recovery of the SBO:Pr/PDMS elastomer film after natural rest periods ranging from 1 min to 24 h at room temperature, following different stretching strains (40%, 60%, and 80%; frequency: 5 Hz). d Interfacial gap width between the SBO:Pr particles and the PDMS matrix under different stretching strains. Insets show the corresponding cross-sectional SEM images
