In order to enhance the viability of this paper for that issue, we suggest adding this to the beginning of the abstract: âBinary semiconductors with (A^IIB^VI and A^IIIB^V) composition and ternary semiconductors (A^IB^IIIC₂^VI and A^IIB^IVC₂^V) composition, owing to their devices such as photonic crystals, wave guides, solar cells and detectors, are technologically important materials. The recent successful fabrication of the blue-green laser diode based on these compounds has renewed interest in their opto-electronic properties. In this paper we present a relationship to evaluate opto-electronic properties such as electronic polarizability (α), refractive index (n), band gap (Eg) and optical electronegativity (Δχ*) in terms of product of ionic charges (PIC) and average atomic number of constituent atoms (Z_av) for zinc blende (A^IIB^VI and A^IIIB^V) and chalcopyrites (A^IB^IIIC₂^VI and A^IIB^IVC₂^V) structured solids. The electronic polarizability (α), refractive index (n), band gap (E_g) and optical electronegativity (Δχ) of these solids exhibit a linear relationship when plotted against the average atomic number constituent atoms (Z_av), but fall on different lines due to the region of product of the ionic charges (PIC) of the compounds. We have applied the proposed relation on these solids and found a better agreement with the experimental data as compared to the values evaluated by earlier researchers so far.
