Tri-color composite volume H-PDLC grating and its application to 3D color autostereoscopic display.

A tri-color composite volume holographic polymer dispersed liquid crystal (H-PDLC) grating and its application to 3-dimensional (3D) color autostereoscopic display are reported in this paper. The composite volume H-PDLC grating consists of three different period volume H-PDLC sub-gratings. The longer period diffracts red light, the medium period diffracts the green light, and the shorter period diffracts the blue light.

Solvent-induced intercluster rearrangements and the reversible luminescence responses in sulfide bridged gold(I)-silver(I) clusters.

Blue or yellow-green emission is observed from two different crystal types of the same gold(I)-silver(I) molecular cluster [SAu(3)Ag(L1)(3)](BF(4))(2) (L1 = 2-diphenylphosphino-4-methylpyridine) depending on the crystallization conditions; structural data suggest that intermolecular Au···Au interactions account for the luminescence vapochromic responses; a similar observation was made on two other pairs of analogues.
