We prepared , -, and - composites by an enhanced method and reported the result of their structural, optical and magnetic properties. In the x-ray diffraction results of the -, and the it is evident that these composites are crystallized in rhombohedral and trigonal structures, respectively. In the- composite, transforms into a trigonal structure with the addition of Dy. The absorption bands belong to , and were obtained using the Fourier transform infrared spectra. In ultraviolet–visible spectra, the photocatalytic properties of - and - were determined as a function of time at room temperature. Maximum transmittance change at 800 nm was 75% and 40% for composites -, and -, respectively. The photocatalytic property of - composite increases gradually from short to long in the wavelength region where it exhibits a maximum value in the visible region. In magnetic measurements, a weak ferromagnetic behavior was observed in the -, while - exhibited paramagnetic behavior as expected. The saturation and coercivity values for - were found to be 0.15 and 40 mT, respectively.
