An iridium(III) complex that exhibits dual mechanism nonlinear absorption

Article Abstract:

The photophysical properties of the complex (L)Ir[(PPY).sub.2.sup.+], where ppy=2-phenylpyridine and L=4,4'-(2,2'-bipyridine-5-5'-diylbis(ethyne-2,1-diyl))bis(N,N-dihexylaniline) were investigated under one and two photon excitation conditions. Solutions of the complex in THF displays nonlinear absorption of 5 ns, 1064 nm pulses in a process that is believed to involve a combination of two-photon absorption and reverse saturable absorption.

Controlled synthesis of high quality PbS star-shaped dendrites, multipods, truncated nanocubes, and nanocubes and their shape evolution process

Article Abstract:

Well defined single crystalline PbS nano- and microstructures including dendrites, multipods, truncated nanocubes, and nanocubes were combined in high yield by a simple solution route. The findings reveal that the desired architecture of building blocks such as star-shaped dendrites and truncated nanocubes can be obtained by programming the growth parameters such as the molar ratio, the initial reaction temperature and period of reaction.

Er-doped lead borate glasses and transparent glass ceramics for near-infrared luminescence and up-conversion applications

Article Abstract:

Lead borate based glasses are analyzed using Raman and infrared spectroscopy along with the Er-doped lead borate glasses. In comparison to the precursor glasses, the luminescence intensities are higher, whereas the half-width of the luminescence lines slightly decreases in transparent oxyfluoride glass ceramics.
