of final products were characterized using X-ray powder diffraction (XRD), scanning electron microscopy (SEM) and photoluminescence (PL). The as-synthesized ZnO is composed of single crystalline and possesses three photoluminescence emissions centered at 400, 469 and 534.5 nm, respectively. Key words: ZnO-nanorod arrays; microwave-assisted synthesis; photoluminescence  ......
in glycol-water mixtures at 170 ℃. The structures and optical properties of the as-prepared samples were investigated using X-ray diffraction, transmission electron microscopy and photoluminescence spectroscopy. The results show that these polyhedrons with average particle size of 20 to 100 nm represent typicle single crystal structures. The photoluminescence (PL) measurements reveal that polyhedron......

The optical properties were studies by ultraviolet-visible diffuse reflectance spectroscopy and photoluminescence measurements at room temperature. The effects of temperature, solvent......
of the glasses were investigated. SrO-ZnO-B2O3-SiO2(SZBS) glass has high transmission capability in visible light region. The excitation peak of SZBS glass locates around 221 nm. The photoluminescence spectrum... hole recombination process, respectively. Besides the excitation peak appears red-shift, the transmission ratio of glasses improves and the blue-green photoluminescence enhances with rare earth oxides......
