General description

Strontium aluminate, europium and dysprosium doped (SrAl2O4:Eu2+,Dy3+) is a mechanoluminescent (ML) phosphor, which can be synthesized by mechanochemical pretreatment. It consists of phosphorescent compounds like europium and dysprosium that provide properties, which include high initial brightness, high quantum yield and chemical stability.
Strontium aluminate, europium and dysprosium doped is a luminescent compound, which can be used in persistent luminous paints, inks, and ceramics. It can be synthesized by a variety of methods such as sol-gel, hydrothermal synthesis, solid-state reactions, and combustion reactions. It can also be utilized in the preparation of efficient bifunctional structural layers for the fabrication of quantum dot dye-sensitized solar cells (DSSCs).

Application

SrAl2O4:Eu2+,Dy3+ can be as a green phosphor for applications in cathode ray tubes, smart textiles, and dye sensitized solar cells (DSSCs).
Long persistent green phosphor
