The effect of the surface coating of a strontium mono-aluminate europium dysprosium-based (SrAlO:Eu,Dy) phosphor by polyethylene (PE), polystyrene (PS) and their dual system on the photoluminescence properties of the pigment.

SrAlO:Eu,Dy as a known strontium mono-aluminate europium dysprosium-based phosphor is widely used in paints and coating formulations as a photoluminescence pigment. It has two major drawbacks: improper dispersion in organic-based paints and weak water and moisture resistance. To address the above-mentioned drawbacks, the surface coating of phosphors with polyethylene and polystyrene individually and in combination using a solution technique was performed.
