Persistent organic compounds: A review

Volatile Organic Compounds Removal Methods: A Review

Volatile Organic Compounds (VOCs) are among the most toxic chemicals which are detrimental to humans and environment. There is a significant need of fully satisfactory method for removal of VOCs. There are several methods including physical, chemical and biological treatments available to remove VOCs by either recovery or destruction. The aim of the present study is to summarize the available m...

Persistent 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 (...

Persistent 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...
