Inorganic phosphors have potential for advanced solid‐state lighting, but their synthesis is complex. J. Jiang, H. Jiang, and co‐workers demonstrate a simple solid‐state reaction for the synthesis of the orthosilicate phosphor Ba 9 Lu 2 Si 6 O 24 :Ce 3+ , which shows an efficient blue–green emission under 400 nm radiation. On page 1096, its internal quantum efficiency (QE) is shown to reach 82%, and 94% of the room‐temperature internal QE is maintained at 160 °C.
