Abstract

The combustion process was used to create an effective ZnAl12O19:Sm3+ phosphor with reddish emission. Using scanning electron microscopy, the structural and morphological characteristics of the phosphor have been studied. Samarium ions are found in trivalent oxidation states, as demonstrated by the photoluminescence spectrum. The as-prepared phosphor exhibits strong visible red emission at 615 nm under 405 nm excitation. It has been discovered that a concentration of 1.5 mol% Sm3+ ions produce the strongest visible red emission. The synthesized phosphors 615 nm (x = 0.680, y = 0.319) and 661 nm (x = 0.730, y = 0.269) CIE colour chromaticity coordinates are located in the red area of the chromaticity diagram. All of these findings support the suitability of Sm3+-doped ZnAl12O19 phosphor for lighting and display applications.
