Abstract

Since the photoluminescence was discovery at room temperature due to the quantum confinement effects, nano-porous materials have addressed intense eye-catching research focuses. The achieved results indicate that besides the superior photoluminescence, nano-porous silicon materials fabricated by the electrochemical approach are promising candidates for the utilizations in biological sensing, energy storage, chemical and catalysis, owing to the correlated biocompatibility, biodegradability, modifiable surface and high porosity, which comprise with tunable optical porous silicon structure and the applications such as biosensing, in vivo imaging, gas sensing and solar cells. Therefore, the facile electrochemical approaches utilized to prepare nano-porous materials are addressed, particularly for nano-porous silicon materials aim to showcase the correlated significant techniques to realize green exploits for the future eco-friendly environmental developments.
