description Opal glass compositions and devices incorporating opal glass compositions are described herein. The compositions solve problems associated with the use of opal glasses as light-scattering layers in electroluminescent devices, such as organic light-emitting diodes. In particular, embodiments solve the problem of high light absorption within the opal glass layer as well as the problem of an insufficiently high refractive index that results in poor light collection by the layer. Particular devices comprise light-emitting diodes incorporating light scattering layers formed of high-index opal glasses of high light scattering power that exhibit minimal light attenuation through light absorption within the matrix phases of the glasses.
