“…As the Eu 2+ ion concentration increases, the shorter wavelength band shows blue-shift, whereas the longer wavelength band shows red-shift. This can be explained based on two aspects: the changing of covalence and variation of the crystal field strength when 0.1 mol of Mg 2+ ions are co-doped into the host lattice [7][8][9]13].…”

“…The Eu 2+ and Mn 2+ co-doped quaternary alkaline earth silicate single-phase phosphor emits warm white light under ultraviolet excitation [5,6]. Eu 2+ (4f 7 ) ion shows a parity-allowed 4f-5d emission varying from ultraviolet to red depending on the host lattice in terms of site size, site symmetry and its coordination number [7,8]. The emission color of Eu 2+ can be controlled by changing the crystal field or the covalence in the host [7].…”

We investigate the influence of the ambient gas during thermal annealing on the photoluminescence (PL) properties of europium compound thin films on Si substrates. The films were deposited by radio-frequency magnetron sputtering and subsequently annealed in N 2 or O 2 ambient gas by rapid thermal annealing (RTA). The results of X-ray diffraction indicate that the resulting europium compound annealed in N 2 ambient have several silicate phases such as EuSiO 3 and Eu 2 SiO 4 compared to those annealed in O 2 ambient. The spectral results revealed that a broad luminescence associated with Eu 2+ ions, with a maximum intensity at 600 nm and a FWHM of 110 nm, was observed from the thin film annealed at 1000°C in N 2 ambient. However, a series of narrow PL spectra from Eu 3+ ions were observed from the film annealed in O 2 ambient.
