Energy flow in manganese-neodymium-doped fluoride glasses
Measurement of the time-response of the excited-state concentration of manganese and neodymium has confirmed our previous hypothesis of fast energy transfer betwen donors and acceptors in fluoride glasses. I. lNTRODUCTION The absorption and fluorescence properties of solid-state materials can often be enhanced by codoping with two ions: one ion (referred to as the donor) which absorbs the energ...
متن کاملneodymium/YAG laser trabeculotomy
Laser trabeculotomies produced by directing a pulsed neodymium/YAG laser beam at specimens of human anterior chamber angle obtained post mortem or after enucleation were studied by light microscopy and by scanning and transmission electron microscopy to assess the dimensions of the openings created in the trabecular meshwork, their penetrance to the canal of Schlemm, and the extent or absence o...
متن کاملThe neodymium neologism.
In 1838, Swedish chemist Carl Mosander isolated lanthanum, a new metal that had been hiding in Berzelius’ cerium since 18031. Two years later, he found yet another metal in cerium — this third component was responsible for a purplish hue in his samples2. He named this metal didymium, from a Greek word meaning twin. Didymium shared many chemical properties with lanthanum and thus appeared to be ...
متن کاملNeodymium neutron cross section measurements.
Neutron capture and transmission measurements were performed by the time-of-flight technique at the Rensselaer Polytechnic Institute LINAC using metallic neodymium samples. The capture measurements were made at the 25-m-long flight station with a 16-segment NaI(Tl) multiplicity detector, and the transmission measurements were performed at 15 and 25 m flight stations with a 6Li glass scintillati...
متن کاملChromium-neodymium Energy Transfer in Yap
Yttrium aluminum perovskite (YAP) co-doped with CI3' and Nd3+ is of interest in laser applications because the chromium-neodymium energy transfer is more efficient in YAP than in YAG. Investigation of the energy transfer from the chromium R lines and pair states in the wavelength range 720-740 nm to the Nd3+ upper laser level shows that neither individual C? ions nor C?+-C? pairs are important ...
