IIn the current work, SrSn(PO4)2 with Mn2+ doped nanopowder was prepared by solid state reaction method at temperature 950K. Mechanically, the equipped nanopowder was characterized by structural, spectral, optical, and luminescence investigations. Crystallite size, phase of the sample was explained by powdered XRD analysis. SEM and HR-TEM analyses provided information about the average particle size of nanopowder, while EDS analysis confirmed elemental composition. The selected area electron diffraction (SAED) pattern confirmed the sample crystalline nature by means of rings corresponding to its XRD planes. FTIR study was explained by fundamental symmetric and asymmetric modes of vibrations. Optical absorption spectrum exhibited the typical Mn2+ bands in visible region. EPR studies revealed the distorted octahedral site symmetry for Mn2+. PL spectrum showed less intense emission region. The evaluated CIE co-ordinate values indicate color precipitation and CCT value is greater than 5000k which reveals that the present Mn2+:STP is useful for warm light LED applications.

“…99 The new Fe 3+ -doped phosphor materials are Sr 9 Ga(PO 4 ) 7 100 and CaCdPH. 101 The predictions for the 2 E energy levels of these Cr 3+ -doped materials and the 4 T 1 energy levels of the Fe 3+ -doped materials were performed using the trained models. The comparison of the model predictions with the actual values of the 2 E or 4 T 1 energy levels is shown in Table 9.…”
