摘要
Sr2-xMgxSi(O,N)(4:)Eu2+ nitridosilicate powders were synthesized using a high-temperature nitridation process. Xray diffraction data and photoluminescence (PL) spectra demonstrated that the Mg2+ ions were incorporated into the Sr(2+ )sites rather than the interstitial sites. The Mg2+ substitution led to a phase transformation and affected the PL properties. There were two Eu2+ sites: Eu(I) and Eu(II). The PL spectra of the Sr2SiO4:Eu2+ powders consisted of two emission bands (A-and B'-bands) in the blue and green regions assigned to Eu(I) and Eu(II), respectively. Remarkably, the Sr2-xMgxSi(O,N)(4):Eu(2+ )powders exhibited an additional emission band (B-band) in the red region, which originated from the large red-shift of the B & PRIME;-band due to the coexistence of the Eu-O and Eu-N bonds. Furthermore, the PL spectra were hypersensitive to the excitation wavelength, resulting in chameleon-like luminescence properties. The PL properties were explained using a structural analysis, multiple Gaussian fit of the spectra, and thermal quenching.
