Photonic materials based on mixtures of cholesteric liquid crystals with polymers

Article Abstract:

Cholesteric liquid crystals (CLC), polymer stabilized cholesteric liquid crystals (PSCLC), and polymer dispersed cholesteric liquid crystals (PDCLC) are promising dye-doped optically pumped lasing materials with an inherent photonic band gap structure. PSCLC/PDCLC can be used as electrically controllable PBG materials as per discovered phenomena's suggestion.

Femtosecond fluorescence up-conversion microscopy: Exciton dynamics in alpha-perylene microcrystal

Article Abstract:

The femtosecond fluorescence up-conversion microscopy method was applied to the study of exciton dynamics in an organic microcrystal, perylene. It was found that exciton dynamics significantly depends on the position in the microcrystal, reflecting the spatial distribution of the defect.
