摘要：
Aluminium doped ZnO (AZO) nanocrystals were prepared under different ambient conditions (argon and air) to study the effect of structural, luminescence and electronic properties. AZO nanocrystals were highly crystallized in hexagonal wurtzite phase with spherical morphology. Prominent yellow emission is observed in both the AZO samples owing to recombination between Al3+ donor levels and intrinsic acceptor centre. Both AZO samples exhibit n-type conduction with resistivity of AZO prepared in inert (argon) ambient condition showing lower resistivity compared to the one synthesized in air atmosphere.
