  ABSTRACT: ZnO short rods with large yield have been synthesized by a simple chemical solution deposition method at a low temperature of 80°C. Polymethyl methacrylate was used as the structure-directing agent in the formation of the rod-like ZnO crystals. X-ray powder diffraction and field emission scanning electron microscopy were used to characterize the obtained product. The results showed that the as-prepared ZnO crystals were rod-like, which have fairly uniform diameter of around 0.5 ∼ 2 μm and length of 4 ∼ 6 μm. A possible formation mechanism of the ZnO rods has been considered.

  ABSTRACT: Amorphous spherical Eu doped YBO3 was synthesized by a mild one-step hydrothermal method. X-ray diffraction (XRD) and scanning electron microscope (SEM) were used to characterize the as-prepared products. It was demonstrated that the use of urea as alkali source plays the key function in the formation of amorphous spherical YBO3:Eu3+. The crystallinity and the morphologies of the YBO3:Eu3+ were sensitive to the urea content and the hydrothermal time. Room temperature photoluminescence (PL) spectra were detected. The sample in uniform diameter of 300–400nm had the relative strong red emissions (R) and R/O ratio of 1.3.

  ABSTRACT: Novel nut-like zinc oxide crystal has been prepared by a low temperature hydrothermal method with the presence of Cu(2+) ion. It seemed that the ultrasonic pretreatment was the key factor during the preparation process. SEM observations revealed that the as-prepared ZnO crystal exhibited nut shape showing well-defined crystallographic facets. The cross-section of the ZnO crystal was hexagonal of about 800 nm-1 microm in diameter, and the aspect ratio was a little smaller than 1:1. The room temperature photoluminescence behavior of the nut-like zinc oxide crystal was much stronger than the reference samples.
