Article Preview

Cr-doped rod-like ZnO particles with nominal 3 at% doping concentration were synthesized by hydrothermal method. The structural and optical properties of the sample were investigated by X-ray diffraction (XRD), field-emission scanning electron microscopy (FESEM) and photoluminescence (PL). The results show that the as-synthesized product is of hexagonal wurtzite structure without metallic Cr or other secondary phases and the morphology of the ZnO particles is rod shaped. The room-temperature PL spectrum of the Cr-doped rod-like ZnO particles exhibits a strong blue emission at 440nm and two weak emission bands centered at 410nm and 565nm, respectively.
