Detection and monitoring of toxic chemical at ultra trace level by utilizing doped nanomaterial.

Composite nanoparticles were synthesized by eco-friendly hydrothermal process and characterized by different spectroscopic techniques. All the spectroscopic techniques suggested the synthesis of well crystalline optically active composite nanoparticles with average diameter of ∼ 30 nm. The synthesiz...
