Preparation of large-size graphene oxide-like with hydroxyl groups and its optoelectronic properties
Source abstract
Abstract
Abstract Laser materials are very important for fabricating laser devices. In this paper, a new type of graphene oxide-like with hydroxyl groups (GOLH) was synthesized for developing pulse laser devices. GOLH was characterized by fourier transform infrared, X-ray diffraction, elemental analysis, scanning electron microscopy, Raman spectra and dynamic light scattering. Experimental results showed that GOLH contained mainly one kind of substituent, hydroxyl group. Average size of GOLH was about 1.5 μm. Its optoelectronic properties were studied by a Q-switched pulse laser. Experimental results suggested that GOLH would be employed as a saturable absorber. A Q-switched pulse laser with the GOLH materials exhibited stable signal intensity and narrow pulse duration, 0.8 μs. Therefore, GOLH would be potential pulse laser materials.
