Abstract
- Pure and Dy-ZnO nanoparticles have been successfully prepared in our experiment.
- XRD, Raman, DRS and PL confirms presence of Dy in ZnO matrices.
- The enhanced green emission demonstrate the increasing of defect concentration with Dy dopant.
- Non existence of Dy emission implies the weak energy transformation of ZnO to Dy in photoexcitation.
- The maximum visible emission can be tuned by varying the excitation energy and dopant concentration.
