Thermally Stimulated Luminescence Excitation Spectroscopy: Application on Measuring the Photoionization Energy of Sr(SCN)2:Eu2+,Used
Delivery time: 8-12 business days (International)
Sr(SCN)2:Eu2+ (Strontium Thiocyanates doped with Europium 2+) shows strong luminescence quenching at relatively low temperatures. It has been suggested that this quenching is due to the thermal promotion of the excited electrons into the conduction band, followed by nonradiative relaxation back to the ground state. In this book we report on experiments to confirm the quenching mechanism in Sr(SCN)2:Eu2+. Because the sample is highly hygroscopic and has to be kept sealed in a quartz vial under an argon atmosphere, the experimental determination of the ionization onset is challenging. We are using thermally stimulated luminescence (TSL) as a noncontact technique to probe the onset between the impurity ground state relative to the host conduction band. We confirm that the quenching in Sr(SCN)2:Eu2+is due to photoionization.
By changing our most important processes and
products, we have already made a big leap forward. This ranges from the
increased use of more sustainable fibers to the use of more
environmentally friendly printing processes to the development of
efficient waste management in our value chain.
