Abstract
In this paper, two-dimensional organic-inorganic hybrid structures with the general formulas of (BA)2PbI4 and (PEA)2PbI4 as the luminescent materials are experimentally investigated. The luminosity properties of the these organic-inorganic hybrid structures are also examined in the absence and presence of coating with thin layers of gold and platinum of 20 nm in thickness at different temperatures ranging from the room temperature to about 106 K under excitation by a light source with the wavelength of approximately 400 nm. According to the observations, illumination in the case of the (BA)2PbI4 structure at 120 K can be enhanced by 12.9 times the illumination at room temperature. In addition, illumination in the case of the (PEA)2PbI4 structure coated with a 20 nm thick platinum layer at 173 K can be enhanced 12.2 times the illumination at room temperature. These results suggest that two-dimensional organic-inorganic hybrid structures (especially (BA)2PbI4 and (PEA)2PbI4 structures) can be useful for the design of novel electronics and optoelectronics devices.
