A blue-green luminescence of SrS:Ce has been known for years. High-density sintered pellets of SrS:Ce were prepared for the first time and their unique spectroscopic properties are reported. A new luminescence band appearing in red and infrared part of spectrum and having all the characteristics of Ce3+ emission was obtained after sintering SrS:Ce at 1700 °C. The excitation features of the regular (blue-green) and the new, anomalous emissions are very much different. Together, both excitations spectra cover the whole range of UV and blue part of spectrum. Such characteristics allow for site-selective excitation of both centers. Experiments in the 25–435 K range of temperatures show that the new, anomalous Ce3+ emitting center hardly interacts with the regular one. Only excitation around 425 nm leads to superimposed emissions of both centers, especially at higher temperatures. Decay traces show that the regular center decay time is pretty constant between 25 and 435 K (shortens from 25 to 23 ns). However, ...
