Research Abstract

High refractive index glasses are key parts for an optical applications, for example digital camera. The refractive index of Ln4Ti9O24 glasses (Ln=La, Nd and Sm) are similar with the indices of Nb2O5 and Ta2O5 thin film (n 2.3). The value is the maximum refractive index of transparent commercial glass materials. The report presents the refractive index calculation of the Ln2O3-TiO2 glasses without using the atomic structure modeling. The isotope enriched neutron diffraction experiments of SmTi2.25O6 glasses has executed. The partial pair distribution function and 3-dimensional atomic configuration of LaTi2.25O6 glass calculated by using Reverse Montel Carlo method reproduce the measured refractive index within +-0.16.
