The present paper reports on the structural and luminescent properties of un-doped and Sm3+ doped Ba2Ca(BO3)(2) phosphors synthesized by the conventional solid state method. For structural characterizations, the X-ray diffraction, FTIR spectroscopy and Rietveld refinement method were used. The FTIR spectrum was composed of basic BO3 and BO4 structural units of borates. The Sm3+ doped phosphors under 402 nm (H-6(5/2)-> L-4(13/2)) excitation, showed an orange red emission corresponding to the 601 nm ((4)G(5/2)-> H-6(7/2)) transition of the Sm3+ ion. An increase in the PL emission intensity was observed up to 2 mol % with the increase in Sm3+ ions concentration. The critical distance between the Sm3+ - Sm3+ ions were found to be 24.36 angstrom. Moreover, the phosphors decaytime and optical bandgap at different concentration of Sm3+ ion also have been discussed in details. All the results show that Ba2Ca(BO3)(2):Sm3+ phosphor may be used with a near ultraviolet (n-UV) chip to fill the amber gap in light emitting diodes (LEDs). (C) 2017 Elsevier B.V. All rights reserved.
