چکیده
This paper reports the detailed preparation process of Eu2+ activated long lasting Sr4Al14O25 nano sized phosphor by precipitation method. Scanning electron microscopy (SEM), simultaneous DSC–TG, X-ray diffraction (XRD), photo luminescent spectroscope (PLS) and thermal luminescent (TL) spectroscope were employed to characterize the phosphor. SrAl2O4:EuDy and Sr4Al14O25:EuDy phosphors in nano scale were obtained by calcinating the precipitated precursor at 1200 and 1300 ◦C, respectively. Both the low-temperature product SrAl2O4:EuDy and t r d a ©

Nanosized strontium aluminate phosphors prepared via a reverse microemulsion route
Nanosized strontium aluminate phosphors co-activated by Eu2+ and Dy3+ were prepared via a novel reverse microemulsion process. This new ynthesis technique lowered the synthesis temperature of SrAl2O4: Eu2+, Dy3+ phosphors to as low as 900 ◦C, and also reduced the particle size o the nanometer scale (around 40 nm). In the microemulsion process, the constituent cations were trapped by numerous na...

متن کاملDevelopment of a Blue Emitting Calcium-Aluminate Phosphor
We report methodological advances that enhance the phosphorescence efficiency of a blue-emitting calcium aluminate phosphor (CaAl2O4: Eu2+, Nd3+). The investigation of long-persistence blue-emitting phosphors is highly desirable due to their promising applications, such as white LEDs; however, the development of highly efficient blue-emitting phosphors is still challenging. Here, we have quanti...
متن کاملEnhancement in Photoluminescence on Mg Substitution in MgxSr1-xAl2O4: Eu, Nd
Strontium aluminate, SrAl2O4 is well-known phosphor host material with spinel structure. Mg substituted compositions, MgxSr1-xAl2O4: Eu, Nd (with x= 0.05 0.25) were prepared by solid-state reaction method. Effect of Mg substitution on structure and photoluminescence was investigated. Prepared compositions were characterized for the phase and crystallinity by powder X-ray diffraction. The micro-...
متن کاملEffect of Composition and Impurities on the Phosphorescence of Green-Emitting Alkaline Earth Aluminate Phosphor
Recent improvements to SrAl2O4:Eu2+, Dy3+ phosphors have enabled the use of luminescent hosts with a stable crystal structure and high physical and chemical stability, thus overcoming the bottleneck in the applicability of ZnS:Cu phosphors. However, enhancement of afterglow lifetime and brightness in SrAl2O4:Eu2+, Dy3+ phosphors remains a challenging task. Here, we have improved the afterglow c...
