The optical properties of the Mg (OH)2 crystalline powder samples, which were prepared by us, were investigated by first-principles method. The calculated results show that the static state dielectric function ε1(0) for Mg (OH)2 is 2.8673. The peak value range for the Mg (OH)2 absorption coefficient is mainly in the energy range from 45.521 eV to 66.0213 eV. Moreover, absorption coefficient researches its maximum, which is 1490460cm-1, at the energy of 63.7988eV. Besides, when energy is greater than 66.3901eV, the reflectivity rate is one. And the average static state refractive rate n (0) for Mg (OH)2 is 1.6292. While the maximum peak of energy loss function for Mg (OH)2 is in 20.4755eV. |
