Photoluminescence properties investigation of germanium inserted biosilica generated by bioreactor culture of marine diatom Nitzschia frustulum

Creator:

Qin, Tian

Abstract:

The purpose of this research was to investigate the optoelectronic properties of the Ge doped biosilica, mainly focused on the photoluminescence (PL) properties of diatom frustules of N. frustulum that contain metabolically inserted germanium oxide produced by a two-stage photobioreactor cultivation process. In order to explain the observed PL intensity...

Characterizations of silicon-germanium nanocomposites fabricated by the marine diatom Nitzschia frustulum

Creator:

Liu, Shuhong

Abstract:

Marine diatoms are a class of microalgae that possess cell walls composed of silica nanoparticles. These organisms actively assimilate silicic acid Si(OH)4 from seawater, polymerize silicic acid to silica nanoparticles by a protein-mediated precipitation process, and then assemble the silica nanoparticles into intricate patterns that constitute the cell wall microarchitecture...
