ABSTRACTCuxO thin films have been deposited on a quartz substrate by reactive radio frequency (rf) magnetron sputtering at different target powers Pt (140-190 W) while keeping other growth process parameters fixed. Room-temperature photoluminescence (PL) measurements indicate considerable improvement of crystallinity for the films deposited at Pt>170 W, with most pronounced excitonic features being observed in the film grown using Pt=190 W. These results corroborate well with the surface morphology of the films, which was found more flat, smooth and homogeneous for Pt >170 W films in comparison with those deposited at lower powers.

A facile and clean fabrication of large-scale ZnO nanorods assisted with Aliquat 336 using aqueous chemical method is reported. As prepared, samples were characterized using XRD, EDS, SEM, TEM, and HRTEM. The optical properties were measured by Raman spectroscopy and room temperature photoluminescence spectra.

Mn doped ZnS nanowires with typical wurtzite single-crystalline structure were successfully synthesized via H2 assistant chemical evaporation deposition method. The investigations indicated that the diameter of Mn/ZnS Nanowire with high aspect ratio is 25~40nm, EDS results show that the content of Mn element is about 4.45at%. HRTEM and SAED results demonstrated that the Mn/ZnS nanowires grow along [101] direction, which was different from the common direction reported in literatures. Room temperature photoluminescence properties were also examined, showing a strong green emission centered at 523.04 nm, and a weak emission at 382.53 nm was also observed, showing a red shift of 45.53 nm comparing to the intrinsic luminescence.
