| Abstract Scope |
Most luminescent materials currently used in modern devices contain rare earth (RE) activators. The increasing demand of REs worldwide is leading to the search for RE-free materials for various applications. In this work, we study a green chemical approach to the production of ZnO luminescent nanoparticles modified with artificial and natural polymer molecules. ZnO nanoparticles were synthesized by low-temperature chemical homogenization methods and their properties investigated. Luminescent emission of the obtained materials is observed in a wide spectral range from 350 to 800 nm. The spectra are complex and consist of two types of spectral contributions. These contributions can be explained by electronic transitions in defect centers induced by the incorporation of polymer molecules in the ZnO crystal structure. The possibility of creating environmentally friendly and lowcost commercial phosphors based on ZnO functionalized with natural biopolymers is discussed. |
