To convert ultraviolet (UV) light into near-infrared (NIR) light in phosphors is demanded for the development of solar cells. A series of NaYF4:Nd3+,Yb3+ white powder samples were prepared via the hydrothermal method. The crystal structure and photoluminescence properties of the samples were carefully studied using X-ray diffractometry (XRD) and photoluminescence spectra. The excitation and emission...
Single-phase multiferroic BiFeO3 and Bi0.9(La/Nd)0.1FeO3 (doped with rare earth ions La3+ and Nd3+) films grown on (111)-Pt/Ti/SiO2/Si substrate were prepared via sol-gel method and a subsequent rapid thermal process. The phase composition, microstructure, ferroelectric, dielectric, ferromagnetic properties were investigated, and meanwhile, the in-plane magnetoelectric (ME) coupling effects of the...
