Structural characterization confirms that all samples crystallize in a single\u2010phase monoclinic lattice, where Sm\n                    <jats:sup>3+<\/jats:sup>\n                    is successfully incorporated into Ca\n                    <jats:sup>2+<\/jats:sup>\n                    sites, inducing slight lattice contraction without destroying the host framework. Spectroscopic analyses reveal that aliovalent substitution generates localized defect states and narrows the bandgap from 3.67 to 3.44\u2009eV, thereby enhancing optical absorption. Under 406\u2009nm excitation, the materials display intense Sm\n                    <jats:sup>3+<\/jats:sup>\n                    \u2010centered emissions dominated by the\n                    <jats:sup>4<\/jats:sup>\n                    G\n                    <jats:sub>5\/2<\/jats:sub>\n                    \u2009\u2192\u2009\n                    <jats:sup>6<\/jats:sup>\n                    H\n                    <jats:sub>7\/2<\/jats:sub>\n                    transition, yielding saturated orange\u2010red output.

In addition, the phosphor exhibits saturated orange\u2013red emission with chromaticity coordinates of (0.5964, 0.4013), highlighting its strong color performance.
