Optically Pumped Lasing Properties Of ZnO Nanorods
The purpose of this study is to investigate the characteristics of optically pumped laser from the ZnO nanorods grown by using the two-step chemical bath deposition (CBD). Samples are grown on two types of substrates, glass and sapphire wafer, AI2O3. Various conditions and treatments of the sampl...

| description |
The purpose of this study is to investigate the characteristics of optically
pumped laser from the ZnO nanorods grown by using the two-step chemical bath
deposition (CBD). Samples are grown on two types of substrates, glass and sapphire
wafer, AI2O3. Various conditions and treatments of the samples have been introduced
to observe the optical emission mainly by manipulating the thickness of ZnO seed
layer thin film and the heat treatment condition. The procedures for CBD process is
fixed for four hours at 97“C for growth process with the solutions of 0.05 M of zinc
nitrate (Zn(NO.3)2.6H2O) and 0.05 M of hexamethylenetetramine (11 MT). Growth
properties of the samples are characterized using field emission scanning electron
microscopy (FESEM) and X-ray Diffraction (XRD). FESEM showed the morphology
of grown nanorods with each sample having their own distinctive size, shape and
population. XRD measurement revealed the information about the crystal structure of
nanorods with a high visible peak at 20 34.4° showing the growth of nanorods is
preferentially along the c-axis and calculation using the XRD data determined the
crystallite size of crystal structure. |
