Optical Characteristics of Porous Glasses Matrix and Its Light-conducted Mechanism

The optical properties of matrix of porous glasses and phase separated glasses were investigated by visible spectroscopy and infrared spectroscopy.The experimental results show that.both the porous glasses and phase-separated glasses hare very good light transmission in visible ligth region that wavelenth is longer than 560nm.The micropores of porous glasses and the boron-rich phase of phase-separated glasses have strong Rayleigh scatter effects on the visible light.the largest scatter occurrs at 360-370nm;the thicker the glasses.the larger the light scattering.Thus .the pore size disribution and thed size of heterogeneous micro zone in boron-rich phase of phase-separated glasses can be measured .After coupled into porours glasses.the most intense absorption of hydrated ious of Co(H2O) 6]^2 shifts from 508 nm to 515nm.The production of the most intense absorption and the red shift were owde to Jahn-Teller of octahedral field formed by six H2O moleculur and perturbation effect resulted by microporous of porous glasses for its physics-chemical cirumstance.As a result.the porous glasses are perfect optical function materials in risible region.ichich can be assembled by chenvical method.

Optical characteristics of porous glasses matrix and its light-conducted mechanism

The optical properties of matrix of porous glasses and phase-separated glasses were investigated by visible spectroscopy and infrared spectroscopy. The experimental results show that, both the porous glasses and phase-separated glasses have very good light transmission in visible light region that wavelenth is longer than 560 nm. The micropores of porous glasses and the boron-rich phase of phase-separated glasses have strong Rayleigh scatter effects on the visible light, the largest scatter occurrs at 360–370 nm; the thicker the glasses, the larger the light scattering. Thus, the pare size distribution and the size of heterogeneous micro zone in boron-rich phase of phase-separated glasses can be measured. After coupled into porours glasses, the most intense absorption of hydrated ions of Co(H₂O)₆]²⁺ shifts from 508nm to 515nm. The production of the most intense absorption and the red shift were owed to Jahn-Teller effect of octahedral field formed by six H₂O molecular and perturbation effect resulted by microporous of porous glasses for its physics-chemical circumstance. As a result, the porous glasses are perfect optical function materials in visible region, which can be assembled by chemical method.
