Plasmon-driven light harvesting in poly(vinyl alcohol) films for precise surface topography modulation

Posted on 05.04.2021 - 20:02
Efficient light harvesting is essential for advanced photonic devices. Light-triggered mass migration can produce complex micro/nano surface relief structures in organic material system but lacks a precise match with light. In this letter, we propose plasmonic harvesting of light energy for the formation of surface relief gratings in polyvinyl alcohol (PVA) matrix. Ultra-small-sized silver nuclei are generated in the polymer by pre-thermal treatment, acting as an accelerator for the subsequent photoinduced particle growth, hydrogen group cleavage, and matrix softening. Based on such properties, complex plasmonic array carrying ultra-high-density information is achieved with peristrophic multiplexing holography. This work paves a bright way to realize data storage, information encryption, and optical microcavity.
