“…For the red phosphor, the line emission from Eu 3+ in Y 2 S 2 O, for example, was found to be an ideal compromise between optimum color coordinates and eye sensitivity. 8,10,11 The development of thin film electroluminescence to be used in display technology was boosted by Vlasenko and Popkov in 1960 12 and the device used ZnS:Mn as the active layer. These devices are generally called ACTFEL and even though the principle was slightly modified due to stability problem in 1967, 13 the resulting device structure is still used to date.…”

A set of multicomponent sulfide-based phosphors of general formula ARES2: 0.05% Eu, where A represents any combination of Rb, K, Na and RE is any combination of La, Gd, Lu and Y, was synthesized in the form of transparent hexagonal crystalline platelets by inorganic reaction under the flow of H2S gas. X-ray diffraction and X-ray fluorescence were employed to investigate their structural properties and intrinsic chemical composition. Optical properties connected to the Eu2+ emission center present in these sulfidic hosts, including photoluminescence excitation and emission spectra as well as the overall emission spectra of circadian light source, were measured by means of luminescence spectroscopy using either PMT or CCD as detection elements. Electron paramagnetic resonance (EPR) was utilized in order to understand the mechanism of the Eu2+ ions incorporation into the ARES2 structure. Important parameters connected to phosphors to be used in solid state white LED technology, such as x,y coordinates in the CIE color space, color correlated temperature (CCT), color rendering index (CRI) and color quality scale (CQS) were calculated from the experimentally obtained emission spectra. Application potential of given phosphors in solid state lighting technology was discussed thoroughly.

“…Overall, a very large variety of spectra and time constants of phosphors are available [19]. Time constants can range from very short (<10 μs) to very long (about 1s).…”

Many processes in electromagnetism vary with time. Some of them are well known, in particular those related to line frequencies of 50 Hz or 60 Hz such as fluctuating light output of discharge and incandescent lamps. The flickers of discharge and incandescent lamps have quite different physical principles involved, which are investigated experimentally using high-speed cameras and theoretically using simplified models. The topic is related to other phenomena such as the transient behaviour of phosphor layers covering the screen of oscilloscopes and the time-varying Lorentz force acting on the filament of light bulbs. All studies are well suited for teaching selected aspects of electromagnetism and light at undergraduate level at university.
