"lithium rare-earth oxonitridolithosilicates' crystal structure: 4-membered silicate rings linked by layered lithium tetrahedra... rare earth activator ions positioned in square-antiprismatic environment coordinated by 4 oxygen/ 4 nitrogen highly efficient anions... lower synthesis temperature, abundant materials... this lithium-based green phosphor LED prototype fabricated/ confirmed competitive with current market standards for green luminescence, as required for ubiquitous white-light LEDs
