Abstract
Forsterite particles doped with europium ions (Eu3+) were synthesized via a solution combustion method. The effect of co-dopants on photoluminescence intensity was described. Different percentages of calcium (Ca2+), zinc (Zn2+), barium (Ba2+) and strontium (Sr2+) were added to the Mg2SiO4:Eu3+ host. The synthesized sample was characterized by X-ray diffraction, transmission electron microscopy, scanning electron microscopy, spectrofluorometer and the FTIR spectroscopy. X-ray diffraction (XRD) results revealed that dominant phase was forsterite in all samples. Additionally, a negligible amount of periclase phase was recognized in the samples. The average size of the synthesized particles was less than 200 nm. The presence of co-dopant led to an enhancement in the photoluminescent property of the synthesized samples. The maximum increase in photoluminescence intensity was obtained by Ba2+ ions as a co-dopant. Condensed films of photoluminescence particles were produced by utilizing electrophoresis technique to deposit particles. The results showed that polyvinyl pyrrolidone was the best surface modifier to raise the mass deposition of the samples on the substrate.
