Abstract:Electron spin relaxation times T 1 and T m of Tb 3+ and Tm 3+ in 1:1 water:ethanol and of Tb 3+ doped (2%) in crystalline La 2 (oxalate) 3 decahydrate were measured between about 4.2 and 10 K. Both cations are non-Kramers ions and have J = 6 ground states. Echo-detected spectra are compared with CW spectra and with field-stepped direct-detected EPR spectra. Due to the strong temperature dependence of T 1 , measurements were not made above 10 K. Between about 4.2 and 6 K T 1 is strongly concentration dependent … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
