Hydrothermal control growth of Zn2GeO4–diethylenetriamine 3D dumbbell-like nanobundles

Abstract

The rational synthesis and design of three-dimensional organic–inorganic hybrids still remain a challenge. A new ZGO-based 3D architecture was successfully fabricated via a facial and controllable hydrothermal method. Influence factors, e.g., feeding ratios, reaction temperature, reaction time show an obvious effect on the morphology of the obtained product. A solvent-coordination molecular template (SCMT) mechanism was proposed to understand the formation of three-dimensional nanobundles based on time-dependent experiments. The composites display a strong and wide emission in 405 and 431 nm, potentially applied in optoelectronic devices and other nanodevices.
