The Al h , s and Kp emission bands of noble and several transition metal aluminides have been investigated. I n the spectra of the alloys long-wavelength intensity peaks are observed which are not present in the spectrum of pure aluminium. The appearance of these peaks is Bseociated with the energy ban& originating from the d-states of the noble and transition metal atoms. For the Al ban& in CuAl,, Cu,Al, and PdAI, the position of the long-wavelength peaks relative to short-wavelength edges is found to correspond approximately to the position of the copper and palladium Lz,s-band peaks with respect to the absorption edges. It is aseumed that the energy region of the d-like bands in the vioinity of aluminium atoms contains an appreciable amount of states arising from the s and p aluminium atom states. This is suggested to be the reaaon for the long-wavelength intensity peaks to appear in the Al Lz,3-and Kp-bands of the alloys.Es wurden die Al-Lz,sund Kp-Emissionsbanden der Edelmetall-und einiger ffbergangsmetallaluminide untersucht. I n den Legierungsspektren wurden einige langwellige Intensitiitsmaxima beobachtet, die in reinen Aluminium-Spektren nicht vorhanden sind. Daa Auftreten dieser Maxima ist verbunden mit Energiebiindern, die von den d-Zuetiinden der Edel-und Ubergangsmetallatome stammen. Fiir die Al-Banden von 014, Cu,Al und PdAl, wird gefunden, daB die Lage der langwelligen Maxima beziiglich der kurzwelligen Kante niiherungsweise mit der Lage der Kupfer-und Palladium-Lz,s-Bandmaxima beziiglich der Absorptionskanten korrespondieren. Es wird die Annahme gemacht, daD der Energiebereich der d-ahnlichen Biinder in der Niihe der Aluminiumatome betriichtliche Beitrage von Zustiinden enthiilt, die aus s-und p-Aluminiumatomzustiinden stammen.Es wird angenommen, daB dies der Grund fiir das Auftreten der langwelligen Intensitiitsmaxima in den Al-h,s-und Kp-Banden der Legierungen auftreten.
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.
