1：Experimental Design and Method Selection:

The phosphor was synthesized via a high-temperature solid-state reaction method in air. The crystal structures and luminescence properties were investigated.

2：Sample Selection and Data Sources:

A series of LiCa(3-x)MgV3O12:xBi3+ (x = 0.0, 0.5, 1.0, 2.0, 4.0, 6.0, and 8.0 mol%) phosphors were prepared.

3：0, 5, 0, 0, 0, 0, and 0 mol%) phosphors were prepared. List of Experimental Equipment and Materials:

3. List of Experimental Equipment and Materials: Chemicals used include Li2CO3, CaCO3, MgO, NH4VO3, and Bi2O3. Equipment includes a Philips Model PW1830 X-ray diffractometer and a MAIA3 TESCAN field-emission scanning electron microscopy.

4：Equipment includes a Philips Model PW1830 X-ray diffractometer and a MAIA3 TESCAN field-emission scanning electron microscopy. Experimental Procedures and Operational Workflow:

4. Experimental Procedures and Operational Workflow: The raw materials were mixed, ground, and heated in a tubular furnace at 700 °C for 5 h, then reground and further sintered at 820 °C for 5 h in air.

5：Data Analysis Methods:

The luminescence properties and decay curves were recorded on a steady-state FLS980 spectrofluorimeter.
