"Production and Characterization of Nanomaterials based on alkaline-earth stannate for different potential Applications”

Abstract

Nanotechnology is a fast-emerging future’s technology, where the nanosized materials have attracted growing interest as a result of their unique structure and properties. Among many applications of nanotechnology that have environmental implications, owing to their outstanding properties, is the nanostructured semiconductors have comprehensive applications in the green chemistry areas such as wastewater treatment and self-cleaning surfaces. Metal stannate MSnO3 and metal hydroxide stannate MSn(OH)6 (M= Ba, Sr, and Ca) nano-semiconductors, which are structurally analogous to the naturally occurring mineral perovskite, have attracted considerable attention due to their use in different optoelectronic application , and greater thermal and chemical stability. Metal hydroxide stannate, MSn(OH)6, are used as precursor materials for making MSnO3, which is used for different applications as anode materials for Li-ion battery and photocatalytic activity. Furthermore, doping europium ion (Eu3+) in Such materials are an attractive option for making efficient luminescence materials used for many optical applications. Upon the above text, the main purpose of this thesis is optimization the preparation conditions such as doping concentration and surfactant as well as adjust pH value to produce a new high photoluminescent lanthanide-based nanomaterials for sensing applications such as latent fingerprint detection, heavy metal detection. Furthermore, coating silver nanoparticle on surface metal – stannate has been investigated intensively in photocatalytic applications for solving environment problems, especially for the removal of organic contaminants with sunlight.
