Abstract

In this work, the structural, thermal, and optical properties of

35 P_{2} O_{5} - 40 Z n O - 25 {N a}_{2} O

−x

{F e}_{2} O_{3}

or y CuO (x = 0, 1, 1.5, 2, 2.5, 3 and y = 0, 1, 3, 4, 5) (mole ratio) glasses was studied. As the molar percentage of

{F e}_{2} O_{3}

and CuO increased, the hardness of the samples decreased. The DTA curves showed that with the increase of

{F e}_{2} O_{3}

and CuO percentage in the glass composition, the glass transition temperature also increased. Adding

{F e}_{2} O_{3}

to 3 mol% decreased the direct and indirect band gaps to 1.906 and 1.887 eV, respectively. The Urbach energy of samples containing CuO increased to 0.550 eV by increasing its amount to 5 mol. Also, the Fermi energy of glasses containing

{F e}_{2} O_{3}

and CuO decreased to 3.144 eV and 3.481 eV, respectively. The results showed that the synthesized samples act as band-pass filters in the visible region and band-stop filters in the ultraviolet region.
