Recently the expressions given by Duffy [17,18] and
Reddy et al.[19–22] correlate the average electronic oxide
polarizability,refractive index,and optical electronegativity
for simple oxides and crystals.However,there is no
systematic data about the correlation between the average
electronic oxide polarizability aO2_ ,optical basicity L,
refractive index n,and optical electronegativity Dw_glass for
binary oxide glasses.
In this paper,we introduce the optical electronegativity
Dw_glass to more complex oxide glass compositions and
extend the approach proposed for simple oxides.We have
estimated the refractive index n,average electronic oxide
polarizability aO2_ ,and optical basicity L on the basis of
the optical electronegativity Dw_glass for binary oxide glass
systems.This type of approach has not been found earlier
in the literature.Hence the inclusion of optical electronegativity
has a wide scope in predicting many physical
properties of optical materials.
2.Results and discussion
2.1.Optical electronegativity of binary oxide glasses based
on the energy gap and refractive index
Optical electronegativity is one of the most important
parameters in understanding the nature of chemical
bonding,and several important physical parameters can
be predicted by using it.Duffy [17,18] has made an attempt
to describe the metallic character of chemical bonding for
compounds that are inadequately described in a solely
‘‘ionic/covalent’’ framework from the point of view of
band gap electronegativity.Optical absorptions for a
semiconductor or insulator arise through electron transfers
from the valence band to the conduction band.The
transfer of electrons from an anion to a cation and the
associated optical absorption is known as ‘‘electron
transfer’’ or ‘‘charge transfer absorption’’.Duffy [17,18]
has well established the above concept and introduced it in
terms of the ‘‘optical electronegativity’’.It has been
recently suggested that a simple model based on the
concept of optical electronegativity and some other
parameters should be good enough to study the main
properties of ionic crystals and semiconductors with the
use of only a few numerical constants.

estimating physicochemical parameters of simple oxides
