“…Since a small amount of Mn 2+ ions can be always present in the prepared ZnAl 2 O 4 as an impurity, it is possible that the observed broad emission around 500 nm has some contribution from Mn 2+ ions. A similar PL emission around 520 nm has been observed earlier in ZnAl 2 O 4 nano-phosphors, wherein it was attributed to defectmediated host lattice emission (Van Die et al 1987;Xiao-Jun Wang et al 2003). The PL emission at 500 nm has been also reported due to Mn 2+ by Singh et al (2008), which corresponds to 4 T 1 -6 A 1 transition of Mn 2+ ions.…”

Sm 3+-doped ZnAl 2 O 4 phosphor was synthesized by citrate sol-gel method and characterized using X-ray diffraction and scanning electron microscopy to identify the crystalline phase and determine the particle size. Photoluminescence (PL) studies on the sample showed emission peaks at 563, 601, 646 and 707 nm with λ ex = 230 nm corresponding to the 4 G 5/2 → 6 H 5/2 , 4 G 5/2 → 6 H 7/2 , 4 G 5/2 → 6 H 9/2 and 4 G 5/2 → 6 H 11/2 transitions, respectively, due to Sm 3+ ions. PL lifetime decay studies confirmed that Sm 3+ ions partly entered into the lattice by replacing Al 3+ ions and remaining located at the surface of ZnAl 2 O 4 host matrix. Thermally stimulated luminescence (TSL) studies of γ-irradiated Sm 3+-doped ZnAl 2 O 4 sample showed two glow peaks at 440 and 495 K, the former being most intense than the latter. The trap parameters were determined using different heating rate methods. Spectral characteristics of the TSL glow showed emission around 565, 599 and 641 nm, indicating the role of Sm 3+ ion as the luminescent centre. A probable mechanism for the prominent TSL glow peak, observed at 440 K, was proposed. CIE chromaticity coordinates for the system was evaluated, which suggested that Sm 3+-doped ZnAl 2 O 4 could be employed as a potential orange red-emitting phosphor.

“…The very strong band at 290 nm can be attributed to the superposition of the 4 A 2 -4 T 1 transition of Mn 4ϩ ions and a charge transfer band. 5,9,11,13 Electron paramagnetic resonance ͑EPR͒ spectra of Mn:YAlO 3 powder samples were recorded with an X-band EMX Bruker spectrometer at room temperature. In such a setup, two types of paramagnetic centers, Mn 2ϩ ions, Sϭ 5 2 , and Mn 4ϩ ions, Sϭ 3 2 can be registered.…”

Manganese-doped yttrium orthoaluminate: A potential material for holographic recording and data storage

et al. 1998

View full text Add to dashboard Cite

Optical properties of manganese-doped yttrium orthoaluminate crystals (Mn:YAlO 3 ), grown by the Czochralski technique, are reported. Luminescence and absorption spectra indicate the presence of Mn 4ϩ ions in as-grown crystals, and Mn 3ϩ , Mn 4ϩ , and Mn 5ϩ ions simultaneously in photoexcited crystals. A permanent diffraction grating, erasable by heating, was obtained in the crystals with diffraction efficiency of more than 50% at 514.5 nm reading wavelength and 1-2 % in 632-930 nm wavelength range. Reading at wavelengths longer than 630 nm did not damage the recorded grating. The electro-optical effect observed in the photoexcited crystals implies that manganese ions disturb the YAlO 3 crystal structure so that it becomes noncentrosymmetric.

“…For this same transition and E/D = 0.00, a resonance line close to 6.0 and a second close to 2.00 may appear. The EPR measurements show that the studied vesuvianite crystals differ in the types of electron defects and in the crystal sites occupied by Fe 3+ (Castner et al 1960;Pan and Nilges 2014;SivaRamaiah et al 2011;van Die et al 1987). It is concluded that, in the pink vesuvianite, Fe 3+ is present in two sites, a tetrahedral site when Fe 3+ → Si 4+ and a second with low symmetry when Fe 3+ substitutes for Al 3+ in Y sites.…”

The absorption- and luminescence spectra of Mn3+ in beryl and vesuvianite

et al. 2017

View full text Add to dashboard Cite

The electron absorption-, photoluminescence-and electron paramagnetic-resonance spectra of Mn 3+ in red beryl from Wah Wah Mountains (Utah USA) and of pink-and purple vesuvianite from Jeffrey Mine (Asbestos, Canada) were measured at room-and low temperatures. The crystal field stabilization energies are equal to 130.9 kJ/mol for the red beryl, and 151.5-158.0 and 168.0 kJ/mol for for the pink-and the purple vesuvianite, respectively. The red photoluminescence of Mn 3+ was not intensive either at room-or at low temperatures. The high Mn content in the crystals caused the emergence of an additional emission band and short photoluminescence-decay lifetimes. The latter are only 183 μs for beryl and 17 μs for vesuvianite.
