摘要：

Aerosol-assisted vapor phase synthesis aimed at preparation of magnetic semiconductor nanopowders of Ga1-xMnxN is carried out both from aqueous and methanol solution mixtures of gallium nitrate and manganese (II) nitrate. After an additional pyrolysis at 1000 degreesC under an ammonia flow, the light colored products are characterized with XRD, SEM/EDX, EPR, BET surface area determinations, helium pycnometry, and oxygen analyses. The characterization data for the powders are consistent with the formation of composites of nanosized manganese-doped hexagonal GaN and regular MnO phases. (C) 2003 Elsevier Ltd.
