Exploration of efficient photoluminescence properties of intense green emitting Er3+ activated NaBi(MoO4)2 phosphor for white LED applications
Source abstract
Abstract
Microcrystalline NaBi(MoO4)2(NBM) phosphors doped with rare-earth ions (Er3+) have been successfully synthesized via conventional solid-state reaction route. The crystal structure, morphology, photoluminescence (PL), and colorimetric properties of NBM: xEr3+samples were explored using various characterization techniques. X-ray diffraction patterns of the as-synthesized phosphors were well-matched with the standard JCPDS (card no. 79–2240) patterns. The peaks centered at 530 (2H11/2→4I15/2) and 552 nm (4S3/2→4I15/2) in photoluminescence (PL) spectra were observed for NBM: Er3+phosphor under 488 nm excitation. The concentration quenching phenomenon in the NBM phosphor was attained at 2.0 mol% of Er3+ion concentration, beyond which it declines the emission intensity. Colorimetric properties of the Er3+activated NBM samples were explored through CIE coordinates, which fall in the green region and indicate high color purity. The aforementioned characteristics demonstrate promising behavior of NaBi(MoO4)2: xEr3+phosphor to use in the field of solid-state lighting applications.Graphical abstract
