A study of optical characteristic of transition metal oxide glasses and switching phenomenon in binary system V2O5 - CdO

In this Study, the glass samples of binary system V2O5 – CdO with different compositions in air with cooling the melt of samples quickly is Conducted. Then the optical absorption spectra of samples in uv-vis region were recorded with an uv-vis spectrophotometer (Cecil –Ce 5501 Model). Eopt and ΔE respectively, are between 1.937ev to 2.730 ev and 0.37ev to 0.57ev are as the V2O5 content decreases from 10 to 25 percent in binary system V2O5 – CdO. Following optical absorption characteristics of binary system V2O5 – CdO the switching phenomenon has been investigated and memory switching at high electrical field was observed.
