摘要：

Mn-doped ZnO was synthesized using a co-precipitation technique. X-ray diffraction (XRD) measurements and photoluminescence (PL) spectra show that Mn ions are doped into the lattice positions of ZnO. The modes at 202, 330, and 437 cm(-1) in the Raman spectrum are assigned as 2E(2) (low), E-2 (high)-E-2 (low), and E-2 (high) modes of ZnO base, respectively. The mode at 528 cm(-1) is ascribed to a local vibrational mode related to Mn. The mode at 580 cm(-1) should be an intrinsic mode of ZnO and assigned to E-1 longitudinal optical (LO). Its reinforcement should result from a combination of resonance at the excitation wavelength and impurity-induced scattering. (C) 2009 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim
