英语翻译Since optical nonlinearity is caused by electronic polar

英语翻译
Since optical nonlinearity is caused by electronic polarizability
of materials on exposure to intense light beams,
electronic polarizability is one of the most important
properties that govern the nonlinear response of the
materials.From Table 1,we can see that conventional
oxide glasses with a high optical elctronegativity possess low
polarizability and optical basicity.Tellurite and titanate
glasses,as well as borate glasses containing a large amount
of Sb2O3 and Bi2O3 with a low optical electronegativity,
show large polarizability and optical basicity.Hence the
glasses containing a heavy metal oxide possess a large linear
refractive index and NLO susceptibility [10].This is due to
the highly polarizable oxide ions in the heavy metal glasses
and the high polarizability of their cations,and this leads to
a high polarizability of the whole molecule and easy
distortions of the electron density in a strong electromagnetic
field.It has been established that third order NLO
susceptibility of binary oxide glasses increases with decreasing
optical electronegativity.
The inclusion of optical electronegativity Dw2glass has a
direct bearing on the concept of chemical bonding [20].The
magnitude of optical electronegativity Dw2glass indicates the
nature of bonding in the materials.If the optical
electronegativity Dw2glass is high,the materials are considered
ionic in nature and if its magnitude is less,the
materials are considered to be covalent in nature.It is also
noticed that for molecules whose optical electronegativity
Dw2 value is less,their refractive index n,electronic
polarizability aO23 ,and optical basicity L are high.From
this study it is possible to correlate the electronic
polarizability aO23 with the optical basicity L,refractive
index n,and the nature of bonding of materials.
3.Conclusions
In this paper,we introduce the optical electronegativity
Dw2glass,to predict basic properties of binary oxide glasses
(phosphate,borate,silicate,germinate,tellurite,and
titanate).Estimations of refractive index n,energy gap
Eg,average electronic oxide polarizability aO23 ,and optical
basicity L on the basis of the optical electronegativity
Dw2glass is a new method and the results are in reasonable
agreements with the results of literature.Hence this
approach may also be used as one of the alternative
methods to estimate the optical basicity L,average
electronic oxide polarizability aO23 and refractive index n
of binary oxide glasses. 赵萍_ii 1年前他留下的回答 已收到1个回答
