Visible Light Activation

Gas sensors based on CaFe2O4 nanopowders, which are p–type metal oxide semiconductor (MOX), have been fabricated and assessed for ethanol gas monitoring under visible light activation at room temperature. Regardless of their inferior sensitivity compared to thermally activated counterparts, the developed sensors have shown responsive sensing behavior towards ethanol vapors confirming the ability of using visible light for sensor activation. LEDs with different wavelengths (i.e., 465–590 nm) were employed. The highest sensitivity (3.7%) was reached using green LED activation that corresponds to the band gap of CaFe2O4.

2D metal oxide fractal structures with different appearance and composition are successfully grown on the silicon (100) substrates from their colloidal solutions at room temperature. These films display very high surface coverage on the substrates and abundant structures. The results demonstrate the appearances and dimensions of these structures are dependent on the properties and composition of their constituent particles and the substrates. This work may have potential applications in the fabrication of gas sensors, photon-receivers and catalyst carriers which are not easy made by other methods at RT.
