Abstract
We developed a rhodamine-B and Au3+ doped PMMA medium for three-dimensional multilayered optical storage. Using the quenching of rhodamine-B by Au3+ ions and the two-photon induced reduction of Au3+ ions to the Au nanoparticle, the developed medium can record and store binary bit data in the form of a fluorescent patterns inside a thick medium. The recorded fluorescent pattern is read out three-dimensionally by using pick-up which incorporates confocal laser scanning fluorescent microscopy
