Optical response spectra of AgnCu13−n+ Bernal spiral clusters show subtle variations by dopant site and loading. Comparison to nanorod-like and icosahedral clusters shows local geometry plays a significant role in electronic transitions at the sub-nanoscale.

Yttrium Aluminum

The optical spectra of fluorinated yttrium aluminum compositions activated by Eu3+ ions were studied. The compositions were synthesized by thermal decomposition at 800 °C of fluorine-containing complexes of yttrium, europium, and aluminum nitrate, isolated as sols from ethyl acetate (EA). The main phases of the compositions are (Y1-xEux)OF and (Y1-xEux)AlO3. Photoluminescence is associated with 5D1,2 → 7F0,1,2 and 5D0 → 7F0,1,2,3,4 electronic transitions of 4f - electrons of Eu3+ ions, replacing yttrium ions in its oxide and oxyfluoride. The dependences of luminescence on the composition and synthesis conditions of the compositions, the wavelength of the exciting radiation, and other factors are established.
