Figure | Dynamic image transformation for anti-counterfeiting displays and optical storage: a Optical microscopic images of the cavity under different humidity states for color variation of laser-printed text information on Sb2S3 layer showing (i) printed UCSD with dynamic color response from top to bottom at different humidity level, (ii) erased optical information under different humidity level (iii) re-printed the word OPTICS with dynamic color response from top to bottom at different humidity level, and (iv) erased optical information under different humidity level. The scale bar is 1 mm. . b The transformation of the UCSD Triton logo and QR code leading to the Ndao lab website (laser printed on the Sb2S3 layer) to the UCSD library logo and QR code leading to ucsd website (patterned on the CMC-N3 layer). The information encoded on the Sb2S3 layer can be clearly read out at a 40% humidity level, while the information encoded on the CMC-N3 layer can be read out at a 85% humidity level (indicated in green dotted lines). The information in other states remained multiplexed or deteriorated due to high humidity. The scale bar is 150 µm.
