Optical Encryption Both wavelength-tunable coloration and light intensity-tunable photoluminescence are independent reliably manipulated in a rewritable dual-responsive encryption display based on block copolymer self-assembly. The has the benefit of being direct intuitive identification encrypted information by human eye, enabling high security anti-counterfeiting.
