FIG. 1.

(a) XRD patterns of the investigated system : a, b, c, d, and e indicate , 0.05, 0.10, 0.20, and 0.30, respectively. (b) Grain size of nanocrystals and ZnO nanoparticles shown as a function of ZnO content in the glass nanocomposites

Image of FIG. 2.
FIG. 2.

(a) Field emission scanning electron micrograph for the composition : larger particles of size corresponds to ZnO nanoparticles and smaller particles of size corresponds to nanocrystals. (b) Transmission electron micrograph for shows ZnO nanoparticles of size . Selected area diffraction pattern is displayed in the inset of Fig. 2(b).

FIG. 3.

FT-IR spectra for different compositions: a ), b , c , d , and e , respectively. Down arrows indicate the peak positions.

Image of FIG. 4.
FIG. 4.

(a) dc conductivity and ac conductivity at different frequencies for different ZnO doped glass nanocomposites at shown as a function of ZnO content. (b) Variation of the dc activation energy of the nanocomposites with ZnO content. For comparison the data for the undoped ZnO glasses are also included in Figs. 4(a) and 4(b).
