Effect of Pb percentage on optical parameters of PbxCd1-xSe thin films

الملخص EN

PbxCd1-xSe compound with different Pb percentage (i.e.

X=0, 0.025, 0.050, 0.075, and 0.1) were prepared successfully.

Thin films were deposited by thermal evaporation on glass substrates at film thickness (126) nm.

The optical measurements indicated that PbxCd1-xSe films have direct optical energy gap.

The value of the energy gap decreases with the increase of Pb content from 1.78 eV to 1.49 eV.
