抄録

Al-doped ZnO nanoparticles with photoluminescence (PL) centered at blue were fabricated through electron beam deposition of Al2Ox and ZnO films on amorphous SiOx surface and annealing in oxygen at different temperatures. The luminescence at near-band-edge (NBE) and deep levels was suppressed by a homogeneous mix of ZnO and Al2Ox. The center peak of 420 nm was shifted to 441 nm in the sample with the nanoparticle size of 10 nm, the characteristics of which were not changed by the oxygen annealing temperature. The decay of PL in Al-doped nanoparticles obeyed a single exponential function and the estimated lifetime was 3.3 ms.
