The invention provides a rare earth ion doped WO x nanorod, a preparation method and an application. Different rare earth ions (La 3+ , Sm 3+ , Eu 3+ , Dy 3+ , Er 3+ , Yb 3+ ) The chloride is dissolved in oleyl amine oleate, and tungsten chloride is added to carry out a heat preservation reaction, and then a cooling treatment is performed to obtain the rare earth ion-doped WO x nanorod; x nanorods undergo surface ligand replacement. The invention can improve the conductivity, carrier mobility and energy band structure of the WO x nanorod through the doping of rare earth ions, and can also realize the conversion of ultraviolet light into visible light, and control the electron transport layer by doping the WO x nanorod with rare earth ions , the introduction of rare earth ion-doped WO x nanorods can not only improve the photoelectric conversion efficiency of the device, but also reduce the hysteresis effect. |
