ZnO nanorods heavily doped with Mo/Er. The effect of post-deposition treatment on defect states and luminescence

Popis výsledku v původním jazyce

This work is aiming at comparison of undoped and the heavily Er, Mo-doped zinc oxide nanorods to find out the peculiarities of the energy and charge transfer and the possibilities of the nanorods improvement. Paramagnetic Er3+, Mo3+ and Mo5+ ions can be detected by means of electron paramagnetic resonance (EPR). Therefore, they can serve as local point probes in the material. Post-growth treatment of the ZnO:Er/Mo by air annealing results in reduction of F+ centers. Red emission appears. EPR results were correlated to the RL, PL and thermally stimulated luminescence (TSL) data as well.n
