摘要: A group of photoluminescent materials, which may have great influence on future fluorescent lamp development, is surveyed. The materials are based hexagonal aluminates and gallates structurally related to the magnetoplumbites (β‐alumina. When activated with Mn2+, Eu2+, Tl2+, Ce3+ , Tb3+ or combinations these ions, they phosphors, some them having a high efficiency good temperature dependence.
