摘要：

Using a simple process of the deposition of ZnO thin films on SiOx/Si substrates and subsequent thermal annealing, we fabricated ZnO quantum dots embedded in silicon oxide matrix. The ZnO quantum dots were characterized using transmission electron microscopy and time-integrated photoluminescence. The photo luminescence of the quantum dots show a blue-shift of 47 meV due to the quantum confinement effect.
