The optical and photoluminescence
properties of ZnO nanocrystals synthesized via hydrothermal method are
determined in this study. The effect of growing time (1 h, 6 h, 12 h,
24 h and 36 h) and Mn concentration (5x10^-4
mol, 10x10^-4, 25x10^-4 mol, 75x10^-4 mol, 100x10^-4
mol, 250x0^-4 mol) on these properties are investigated and presented
in detail. Optical properties of the nanocrystals are investigated by using
UV-VIS spectrophotometer. The ultraviolet–visible (UV-Vis) and
photoluminescence (PL) spectroscopy techniques are used for optical and
photoluminescence properties characterization. Room temperature PL
spectra of the ZnO nanopowders show a near band-edge emission (peak at 385 nm)
and a red light emission (peak at 650 nm) for both ZnO synthesized for different
growing time and different Mn concentration. The ZnO prepared with 1 h and 12 h includes the lowest oxygen related
defects. The ZnO doped with 5x10^-4
mol shows the highest oxygen related defects whereas that of 100x10^-4
mol shows the lowest defects.
