摘要: Abstract Al doped ZnO nanorods (NR's) having concentration up to 10 mol% were grown by the hydrothermal method. XRD measurements showed that substituted NR's maintained hexagonal wurtzite structure for all levels of substitution. EDX ZnO:Al indicated substitution created additional Zn vacancies in which is reflected enhanced photoluminescence emission visible light spectra between 450 and 550 nm more heavily NR's. SEM images heavier nano nodules being formed on surface shaped The saturation magnetizations as measured a SQUID magnetometer increased 10.66×10 −4 emu/g was in. hysteresis loops began exhibit novel effects, such horizontal shift (exchange bias field 0.0382 kOe 9 mol% NR) butterfly shapes.
