UVC ML mechanism. a UVC ML emission spectra of SBO:Pr phosphors embedded in different matrices (ER, PU, SG, and PDMS) under rubbing stimuli. Insets show the corresponding UVC ML images. b Triboelectric potential of the ER, PDMS, PU, and SG after rubbing with the SBO:Pr phosphor under 120 rpm for 1 min. c UVC ML emission spectra of SBO:Pr/PDMS elastomer film with varying mass ratios of release agent to PDMS. The insets show UVC ML images of the film containing 0 and 10% release agent. d Simulated electron-gain (yellow) and electron-loss (light-blue) regions at the SBO-PDMS monomer interface. e Schematic diagram of the proposed UVC ML mechanism of the SBO:Pr/PDMS elastomer film under mechanical stimuli
