Abstract
In this work, a ternary metal oxide nanomaterial (Zn2GeO4) has been prepared by the combination of laser ablation in liquid and hydrothermal method. The effects of hydrothermal time and temperature on the microstructure and size of Zn2GeO4 has been studied. The results shows that the change of hydrothermal temperature has a great effect on the crystallization of the product, while the change of reaction time has no obvious effect on the quality of the product. The analysis of UV-VIS absorption spectra shows that the band gap of synthesized Zn2GeO4 is 4.58 eV, which is suitable for UV detection. Finally, we tested the UV detector based on Zn2GeO4 nanomaterial, and found that the conductivity of the material increases significantly with the increase of the irradiation laser intensity, indicating that the material has excellent photosensitivity and detection ability.
期刊介绍:
Optical Materials has an open access mirror journal Optical Materials: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review.
The purpose of Optical Materials is to provide a means of communication and technology transfer between researchers who are interested in materials for potential device applications. The journal publishes original papers and review articles on the design, synthesis, characterisation and applications of optical materials.
OPTICAL MATERIALS focuses on:
• Optical Properties of Material Systems;
• The Materials Aspects of Optical Phenomena;
• The Materials Aspects of Devices and Applications.
Authors can submit separate research elements describing their data to Data in Brief and methods to Methods X.
