Luminescence Properties of Eu and Mn Doped Sr2MgSiO5 Phosphors
Eu ions doped Sr2MgSiO5 phosphors, and EuMn ions-doped Sr2MgSiO5 phosphors were prepared via high-temperature solid state reaction method and sol-gel process, respectively. Luminescent mechanism and characteristics of all samples were studied. The results showed that lattice structure of Eu ion-doped Sr2MgSiO5 samples was pyramidal system. The influence of flux on luminescence properties of Eu ...
متن کاملMn-doped ZnS nanoparticles as efficient low-voltage cathodoluminescent phosphors
We have synthesized nanoparticles of ZnS doped with Mn for potential use as cathodoluminescent phosphors in field-emission displays ~FEDs!. We show that the cathodoluminescent efficiency of particles <100 nm in diameter is within 40% of that of a commercial ~micron-sized! phosphor when the electron-beam energy ranges between 500 and 3500 eV. The nanoparticles exhibit less current saturation tha...
متن کاملPhotoluminescence behavior of Ti-doped Zn2SiO4 thin film phosphors
This work investigates the luminescent properties and structure of Zn2SiO4:Ti thin-film phosphor, before and after annealing up to 1000C. The Zn2SiO4:Ti films are fabricated by RF sputtering using ceramic target. After annealing at 800C the β-Zn2SiO4 phase is formed, but this phase is not suitable for the application in electroluminescence. The willemite structure (α-Zn2SiO4) is formed after an...
متن کاملRadioluminescence of red-emitting Eu-doped phosphors for fiberoptic dosimetry.
Fiberoptic dosimetry (FOD) technique has become an attractive method for real-time dosimetry. Al(2)O(3):Cis one of the most used radioluminescence materials for FOD due to its high efficiency but it presents the drawback of emitting in the spectral region, where spurious luminescence is also important. Optical filtering is the simplest technique to remove spurious luminescence, but is useful wh...
