FIG. 1.

Typical SEM image for the undoped ZnO (a) and EDS spectrum for the ZnO nanostructures doped with 1% Yb (b).

Image of FIG. 2.
FIG. 2.

TL glow curves taken after irradiation at indicated doses: (a) undoped ZnO and (b) 5% Yb doped ZnO.

FIG. 3.

Computer deconvoluted of TL glow curves for undoped ZnO (a) and ZnO doped with 5% Yb (b) exposed to of beta radiation. ZnO displays two TL glow peak components at (second order) and (first order), with activation energies of 0.8 and . The TL glow curve of ZnO:Yb (5%) shows a first order peak at with an activation energy of .

FIG. 4.

Dose dependences of the peak areas: (a) undoped ZnO and (b) ZnO doped with 5% Yb.
