Abstract: Long after-glow luminescent composites were fabricated by embedding phosphor SrAl 2 O 4:Eu 2+ , Dy 3+ powders into polymethyl-methacrylate (PMMA) using solution casting and hot-press methods. In the first method, PMMA were dissolved in chloroform forming a homogenous solution and the phosphor powders were doped into the solution with different volume fractions. Transparent samples were obtained by air drying the solution in a container. Their optical properties were studied by transmittance measurement and emission spectroscopy. For tensile and impact tests, samples were obtained by pressing mixed phosphor and PMMA powders at 190°C. Based on these studies, the mechanical and optical properties of these composite were investigated.
