Abstract

The thickness and size-dependent characteristics of MoS2 nanosheets lead to the use of this material for basic science research and industrial applications. Until the date, scalable production of MoS2 nanosheets without the addition of any surfactant and hazardous chemicals remains challenging. Our study reports the synthesis of a few layers of MoS2 nanosheets by the use of the liquid-phase exfoliation technique. As-synthesized nanosheets were characterized by UVVisible spectroscopy, atomic force microscopy (AFM), photoluminescence (PL) and Raman spectroscopy techniques. Our straightforward and efficient preparation directs to very strongly blue luminescing nanosheets. [ABSTRACT FROM AUTHOR]

Abstract

We report the room temperature ferromagnetism in 2% Cu doped ZnO films grown by RF magnetron sputtering in different argon and oxygen partial pressure. X-ray photoelectron spectroscopy was used to ascertain the oxidation states of Cu in ZnO. The presence of defects within Cu-doped ZnO films can be revealed by electron paramagnetic resonance. It has been observed that saturated magnetic moment increase as we increase the zinc vacancies during deposition. [ABSTRACT FROM AUTHOR]
