Research Abstract

TiO2-, N2bO5-, Ta2O5-, W3O-, or L2Oa3-based high refractive indelxassges were fabricatedby containerless processi.ngThey have a high refractive index in the visible region withlow wavelength dispersion. We suggested that the high refractive wasindeaxresult of high polarizability of oxygen ions causedglasbsy high iconicity.componentswith
