This research found that doping ZnO with Mg2+ can control its fluorescent properties, and a low-temperature manufacturing process can avoid the reduction of fluorescent efficiency. Zn1-XMgXO quantum dot solution prepared by a sol-gel method can be precipitated and re-dissolved after purification.
This research found that ZnO doping with Mg2+ can control its fluorescent intensity, energy gap and fluorescent wavelength. The non-high temperature manufacturing process (50 ?C) can also avoid the reduction of fluorescent efficiency to a certain extent. A simple sol-gel method is used to prepare a transparent Zn1-XMgXO quantum dot solution, and the product is precipitated by a direct precipitation method. After purification, the Zn1-XMgXO quantum dot powder are obtained, which can be re-dissolved into the solution. The results show that the doping of Mg(2+ )in ZnO led to the increase of fluorescent intensity and energy gap. Also, with the increase of doping ratios, the PL intensity increases and the emission bands are slightly blue-shifted.
