Outline of Final Research Achievements

We have completed the set target to optimize the defects in oxides and examine the wavelength conversion and demonstration of a “plasmon-mediated photoelectric transfer”. With suitable combinations of plasmonic metal (TiN/Au) and oxides/nitrides (GeO2/C3N4), we demonstrated the near IR light induced photocurrent generation and photocatalytic chemical reactions for water splitting. The defect-mediated broad-band NIR upconversion is still under investigations. The work on optimization of defects in GeO2/Ge pyramids structure, NIR light induced photocurrent generation and TiN/carbon nitride composite have been presented in various conferences/meetings (S. L. Shinde et. al. IUMRS-ICAM, Aug. 2017; ISSS-8, Oct. 2017; MANA International Symposium, March 2018) and published in peer-reviewed journals (S. L. Shinde et. al. ACS Photonics 2017 (4), 1722, ACS applied materials & interfaces 2018 (10), 2460).
