DIRECT LUMINESCENCE AND THERMALLY STIMULATED LUMINESCENCE OF 4H CdI2
Direct luminescence (DL) spectra of 4H Cd12 in the spectral region 1.8-3.4 eV at temperatures between 9.3 and 215 K and thermally stimulated luminescence (TSL) spectra are reported. The DL spectra consist of several overlapping broad emission bands. These bands are due to radiative recombination of localized (trapped) electrons with localized (trapped) holes. With a simple theory, which takes i...
متن کاملEffect of LiCl on the Microstructure and Luminescence Properties of YVO4:Eu3+ and YBO3:Eu3+ Phosphors
In this investigation, Eu3+ doped YVO4 /YBO3 phosphors were synthesized individually by conventional solid state method at 1100 °C under atmosphere condition. Meanwhile, different amounts of LiClwere used as the flux compound to modify the morphology of the phosphor particles and also final luminescence properties. It was concluded that even small amounts of fluxes play a vital role in the grow...
متن کاملRed, Green, and Blue Photoluminescence of Ba2SiO4:M (M = Eu3+, Eu2+, Sr2+) Nanophosphors
Divalent europium doped barium orthosilicate is a very important phosphor for the production of light emitting diodes (LEDs), generally associated to the green emission color of micron-sized crystals synthesized by means of solid-state reactions. This work presents the combustion synthesis as an energy and time-saving preparation method for very small nano-sized Ba₂SiO₄ particles, flexibly dope...
متن کاملPersistent Luminescence in Eu2+-Doped Compounds: A Review
In 1996, Matsuzawa et al. reported on the extremely long-lasting afterglow of SrAl2O4:Eu 2+ codoped with Dy 3+ ions, which was more than 10-times brighter than the previously widely used ZnS:Cu,Co. Since then, research for stable and efficient persistent phosphors has continuously gained popularity. However, even today almost 15 years after the discovery of SrAl2O4:Eu 2+ , Dy 3+ the number of p...
متن کاملPersistent Luminescence in Non-Eu2+-Doped Compounds: A Review
During the past few decades, the research on persistent luminescent materials has focused mainly on Eu2+-doped compounds. However, the yearly number of publications on non-Eu2+-based materials has also increased steadily. By now, the number of known persistent phosphors has increased to over 200, of which over 80% are not based on Eu2+, but rather, on intrinsic host defects, transition metals (...
