1：Experimental Design and Method Selection:

The study involved the synthesis of Nd3+ doped Mg2SiO4 nanophosphors using a low temperature solution combustion technique at 350°C. The methodology included the use of magnesium nitrate, neodymium nitrate, fumed silica, and oxalyl dihydrazide as fuel.

2：Sample Selection and Data Sources:

Stoichiometric quantities of raw materials were used for synthesis. The samples were characterized without any post calcination.

3：List of Experimental Equipment and Materials:

Equipment used included a muffle furnace, X-ray diffractometer, SEM, TEM, FTIR spectrophotometer, diffuse reflectance spectrophotometer, spectrofluorometer, and TLD reader.

4：Experimental Procedures and Operational Workflow:

The synthesis involved dissolving raw materials, stirring, combustion in a muffle furnace, and grinding the obtained powder. Characterization techniques were applied to study the structural, morphological, and optical properties.

5：Data Analysis Methods:

Data analysis included PXRD for phase identification, SEM and TEM for morphology, FTIR for functional groups, PL for emission properties, and TL for dosimetry applications.
