Anti-counterfeiting holographic liquid crystal gels with color and pattern control
Abstract
Optically tunable and switchable reflection grating LC gels can be used in anti-counterfeiting materials for optical security and encryption. Reflection colors and patterns appear by applying an AC field and a DC field controls the holographic color of the samples.
