“…The spectra were measured with a spectral resolution of 0.5-1.0 nm. The complete set-up was described earlier [16]. Luminescence life time measurements were measured using a Lambda Physik dye laser pumped by a Lambda Physik LPX100 excimer laser (operating at 308 nm) for pulsed excitation at 450 nm using a Coumarin 47 dye.…”

The optical properties of SrSi 2 O 2 N 2 doped with divalent Eu 2+ and Yb 2+ are investigated. The Eu 2+ doped material shows efficient green emission peaking at around 540 nm that is consistent with 4f 7 -4f 6 5d transitions of Eu 2+ . Due to the high quantum yield (90%) and high quenching temperature (4500 K) of luminescence, SrSi 2 O 2 N 2 :Eu 2+ is a promising material for application in phosphor conversion LEDs. The Yb 2+ luminescence is markedly different from Eu 2+ and is characterized by a larger Stokes shift and a lower quenching temperature. The anomalous luminescence properties are ascribed to impurity trapped exciton emission. Based on temperature and time dependent luminescence measurements, a schematic energy level diagram is derived for both Eu 2+ and Yb 2+ relative to the valence and conduction bands of the oxonitridosilicate host material. r

“…It possesses high quantum efficiency (around 80%), good chromaticity, and strong absorption in the vacuum ultraviolet excitation band, making it widely used in three-band fluorescence lamps, plasma display panels (PDPs), and white light-emitting diode (LED). [1][2][3][4] However, the oxidation resistance of BAM is rather poor. The BAM phosphor will undergo a decrease of luminescence intensity during post-treatment processes, for example, irradiation by ultraviolet photons, ion sputtering, and baking process in air during PDP manufacture.…”

Enhanced Optical Performance of BaMgAl₁₀O₁₇:Eu²⁺ Phosphor by a Novel Method of Carbon Coating

Many strategies have been adopted to improve thermal degradation of phosphors. Because of the stability and high transmittance of graphene, here we report a novel method of carbon coating on BaMgAl 10 O 17 : Eu 2+ (BAM) phosphor particles through Chemical Vapor Deposition (CVD). The chemical composition, microstructure, and luminescence performance of carbon-coated BAM were characterized carefully. This coating can be controlled within 3-10 atomic layers, depending on the reaction time. Due to the decrease of surface defects and the effective weakening effect of oxidizing Eu 2+ to Eu 3+ after

“…1 They are excellent host materials for solid state lasers 2 and improved phosphors. 3,4 They have high thermal stability and toughness suitable for their application in refractors or abrasives. 5 At ambient, the RE oxides exist in three polymorphic phases: for large cationic radius (La to Nd), the hexagonal phase designated as the A-type with a space group P3m1 is the most stable; for the medium cations (Sm to Gd), the monoclinic phase designated as B-type with space group C 2 /m is preferred; and for the small cations (Tb to Lu), the cubic-phase designated as C-type with space group I a3 is the most stable.…”

The investigation of structural phase transition and anharmonic behavior of Yb2O3 has been carried out by high-pressure and temperature dependent Raman scattering studies respectively. In situ Raman studies under high pressure were carried out in a diamond anvil cell at room temperature which indicate a structural transition from cubic to hexagonal phase at and above 20.6 GPa. In the decompression cycle, Yb2O3 retained its high pressure phase. We have observed a Stark line in the Raman spectra at 337.5 cm−1 which arises from the electronic transition between 2F5/2 and 2F7/2 multiplates of Yb3+ (4f13) levels. These were followed by temperature dependent Raman studies in the range of 80–440 K, which show an unusual mode hardening with increasing temperature. The hardening of the most dominant mode (Tg + Ag) was analyzed in light of the theory of anharmonic phonon-phonon interaction and thermal expansion of the lattice. Using the mode Grüneisen parameter obtained from high pressure Raman measurements; we have calculated total anharmonicity of the Tg + Ag mode from the temperature dependent Raman data.
