Diatom microalgae as sustainable sources of high-quality photonic crystals with tailored emission properties

On demand | Presented live 9 April 2024

Abstract

The high and unique demand for materials and their processing in nanophotonic technologies negatively impacts the environment. In this context, using biological systems as sources of photonic nanomaterial arose as an efficient alternative for light manipulation at the nanoscale, providing high-quality and sustainable materials for nanotechnological applications. Within the vast family of biomaterials suitable for photonic application, diatoms are one of the most attractive options due to their nanostructured biosilica exoskeleton – the frustule. Diatoms are a group of unicellular photosynthetic microalgae living in most aquatic and humid habitats. They naturally produce a species-dependant nano-porous pattern in their silicate-based frustule, which is easy to isolate and, therefore, easy to use as scaffolds for nanophotonic applications. In this paper, we introduce diatoms as a source of high-quality slab photonic crystals with incorporated micro-photoluminescence properties, which opens the doors for high-quality bio-produced emission devices.
