| Popis: | Here we are reporting sol–gel synthesis diluted magnetic (Er, V)-co-doped ZnO nanocrystals as a dilute semiconductor. The structural and morphological properties were studied using some techniques such as X-rays diffraction (XRD) and transmission electron microscopy (TEM). The optical properties were characterized by Spectrophotometer UV–Visible–IR and photoluminescence (PL). The structural properties showed the appearance of wurtzite structure with a crystallite size around 45 nm and a secondary phase has been detected, attributed to Erbium complex. Raman measurements show that the good quality of the crystals is also maintained after doping, which is confirmed by the coexistence of the polar and non-polar modes E1 and E2, respectively. The increase in the doping concentration of Er caused a decrease in band gap energy. PL shows the appearance of some defects between the valence and conduction band of ZnO linked to doping with Er. |
