Synthesis and characterization of properties of zinc coated Thaumatococcus daniellii extracts for solid state application

Abstract

Abstract Recent technological inventions focus on the eco-friendly device that would not constitute hazard to immediate environment i.e. both in the short and long term. This research focus on screening bio-semiconductor using synthesized zinc coated Thaumatococcus daniellii extract. The band gap of sample 1 (extract in methanol solution), sample 2 (extract in ethanol solution) and sample 3 (extract in butanol solution) was calculated as 2 eV, 1.67 eV and 2 eV respectively. Also, the low and high Q-transition energy in the ethanol and butanol solution was able to show that the d-shell (d10) of the zinc atom was modified. This modification is a huge possibility of deriving bio-semiconductor from plant extract.
