Title

Samarium doped KMgBO3 phosphors for orange-red light emission

Abstract

To improve orange-red color releasing phosphor material with white light emitting diodes (W-LEDs), 2mol%, 4mol%, 6mol% and 8 mol% of Sm3+ ion doped in KMgBO3 phosphor materials were made up with solid state technique. Their structural, morphological, optical along with emission characteristics of produced powders have been studied using XRD, FTIR, SEM, Uv-Vis-NIR spectrometer along with fluorescence spectrometer. This XRD spectra shows the crystal structure of KMgBO3: Sm3+ phosphors is single phase cubic through P213 space group. From excitation spectra, the prominent excitation band observed at 6H5/2→4F7/2, this transition has been utilized to get emission spectra. The emission spectra consist of 4G5/2→6H5/2, 6H7/2 and 6H9/2 transitions corresponding to the Sm3+ ion. This intense emissions band was noticed on 4G5/2→6H7/2 among all these luminescence transitions. The CIE, CCT and decay life time values were computed and analyzed. All of these findings strongly suggested the produced phosphor materials are useful for orange-red color emission component in W-LEDs along with displaying devices.
