The luminescence study of Sr0.98Li2.5 + zAl1.5 – zO3 + 2zN1 – 2z:0.02Eu coumpounds.

Description

Eu²⁺-doped UCr₄C₄-type oxynitride phosphors are emerging innovative materials to replace oxide and nitride phosphors for high-end light-emitting devices. A series of Sr_0.98Li_2.5 + zAl_1.5 – zO_3 + 2zN_1 – 2z:0.02Eu phosphors were synthesized by collaborators from the National Taiwan University by precursor engineering, and these products showed an unexpected redshift from 583 to 620 nm. The effects on photoluminescence from the first-shelled O/N ligands and the second-shelled Li/Al ions were demonstrated in detail. Finally, the light-emitting diode packages constructed using our phosphor revealed higher luminous efficiency of radiation and luminous efficacy than the SrLiAl₃N₄:Eu comparator. This study provided the basis for developing novel oxynitride phosphors and insights into the structural analysis from the macro and micro perspectives.

In that dataset, the scientific article with Supporting Information, raw data of excitation and emission spectra, and temperature-dependent photoluminescence and decay profiles are provided.
