Porous silicon synthesis to produce nanostructures and its use as a template to confine malachite green

verfasst von: Pushpendra Kumar, Rohit Upadhyay, Ronak Goyal, Peter Lemmens, Rajendra P. Joshi
Abstract: Nanomaterials have been a topic of interest for nanoscience and nanotechnology, which is an ever-growing multidisciplinary field of study, attracting tremendous interest, investment, and effort in research and development. Nanoporous materials are a subset of nanostructured materials and possess distinctive properties for several applications. Among the series of porous materials, porous silicon (PS) has been a material of great interest because of its easy synthesis by electrochemical methods and better control on physical properties, e.g., porosity, pore diameter, and length. In this work, the electrochemical method is used to produce PS of various physical properties in hydrofluoric acid (HF) based solution and these PS are used to make silicon (Si) nanoparticles. Further, the PS is used as a template to study the confinement effect on the optical properties of malachite green. Various spectroscopic techniques are used to study the properties of impregnated PS and Si nanoparticles. Spectroscopic and microscopic results were explained using quantum confinement phenomena. The Si nanoparticle is a prominent candidate for investigation and applications in luminescence display devices for their broader excitation spectra, in solar energy cells, bio-imaging, hydrogen generation, body armor in defense, and micro and integrated semiconductor devices.
