Abstract:Es wird gezeigt, dab die Abklingung der Alkalipolysulfid-und Uranylsalzphosphore bei allen Temperaturen exponentiell verlituft und dab die Zeitkonstante T der Abklingung bei allen Phosphoren mit h6herer Temperatur abnimmt. Das Emissionsspektrum yon vier Uranylverbindungen wird bei + 20 ~ C und --180 ~ C angegeben. Der Temperaturverlau~ der Quantenausbeute ist bei allen Phosphoren yon der Erregungsintensit~t unabh~ingig, eine Thermolumineszenz konlite nicht entdeckt werden. Die MeBergebnisse best~tigen den mono… Show more
“…With increase in the atomic weight of the metal of the sulfide and also with decrease in temperature, emission shifts to longer wave length and the decay constant decreases. This is taken to denote stronger coupling within the molecule, with consequent lower probability for radiationless transitions (65).…”

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.
