Pulsed Laser Ablation of Tin Oxide Nanoparticles in Liquid for Optoelectronic Devices

Tin oxide nanoparticles with a narrow size distribution were prepared by pulsed laser ablation of a pure tin target both in aqueous solutions and in pure water. Laser beam of 266 nm, 355 nm and 532 nm from an Nd :YAG laser were applied and the wavelength effects on preparation of tin oxide particles were examined. The particle size and phase structure were characterized by using transmission electron microscope (TEM). The observation revealed that the particle size of the nanoparticles was about 2–5 nm. Chemical components of obtained nanoparticles were analyzed by using an energy dispersive X-ray analysis (EDX) and the results demonstrated that the nanoparticles mainly consisted of Sn and O elements. Furthermore, aqueous solutions of sodium dodecyl sulfate (SDS) were used to study the influence of surfactant concentration on the formation of tin oxide nanoparticles. When the surfactant reached critical micelle concentration, relatively stable colloidal suspensions consisting of well-dispersed tin oxide nanoparticles were obtained. UV-vis spectrometer was used to measure the absorption of suspensions of tin oxide nanoparticles.

The tunable photoluminescence (PL) property is very important for gallium nitride (GaN) nanoparticles in the application of ultraviolet and blue optoelectronic devices, while conventional methods are not so satisfactory that alternative methods for preparing GaN nanoparticles should be studied. In this paper, ultra-small and well dispersed GaN nanoparticles are fabricated through femtosecond pulse laser ablation in air, water and ethanol. For the PL spectra of GaN nanoparticles, there are no shifts in air, red shifts in water and blue shifts in ethanol compared with the intrinsic PL spectra of bulk GaN. The X-ray photoelectron spectroscopy (XPS) results demonstrate that the various PL spectra can be due to the different components inside the GaN nanoparticles, which not only have effect on the PL emissions, but also greatly influence the intensity of PL. This study validates that the ablation environment has a great adjustable effect on the properties of GaN nanoparticles.
