Excitons with charge transfer in sncl2-phthalocyanine films [PDF]

ISSN 0503-1265. Ukr. J. Phys. 2007. V. 52, N 1 pp. 53-59, 2014
The absorption, modulated photoreflectance, and photovoltage spectra of dichlorotin phthalocyanine (SnCl2Pc) films have been measured. These films are thermally deposited in vacuum at different substrate temperatures. The energies of charge-transfer-states (CT-states) in SnCl2Pc films (1.35, 1.52, and 2.05 eV) and the diffusion length of Frenkel ...

Unlocking Multimodal Nonlinear Microscopy for Deep‐Tissue Imaging under Continuous‐Wave Excitation with Tunable Upconverting Nanoparticles

Advanced Materials, EarlyView.
This study introduces a multimodal nonlinear microscopy approach using upconverting nanoparticles (UCNPs) under continuous‐wave excitation. The UCNPs exhibit high‐order nonlinear optical responses, enabling deep‐tissue 3D imaging, video‐rate wide‐field imaging, and depth‐selective photomodulation.

Photosensitive Polyimide using Fullerene as Photosensitizer.

Journal of Photopolymer Science and Technology, 2000
Highly thermo-stable photosensitive polyimides were prepared from the new diamine monomer containing a furan moiety. UV irradiation and development of the photosensitive polyimide in the presence of a fullerene as a sensitizer afforded good quality patterns. Post-exposure baking was found to improve its photosensitivity.

Elucidation of the Relationships between H-Bonding Patterns and Excited State Dynamics in Cyclovalone

Molecules, 2014
Cyclovalone is a synthetic curcumin derivative in which the keto-enolic system is replaced by a cyclohexanone ring. This modification of the chemical structure might in principle result in an excited state that is more stable than that of curcumin, which
