Anisotropic Optical Properties of Thin-Film Thiacarbocyanine Dye Aggregates
Optical properties of thin films of aggregated thiacarbocyanine (TCC) dyes have been studied by means of spectroscopic ellipsometry and polarized IR spectroscopy. The experimental results reveal a strongly anisotropic response of the films, as quantified in the reported anisotropic dielectric functions over a wide range of frequencies. The studied TCC films exhibit both J-aggregate and H-aggreg...
متن کاملSelective mode excitation in dye-doped DNA polyvinyl alcohol thin film.
A solid-state laser based on a dye-doped deoxyribonucleic acid (DNA) matrix is described. A thin solid film of DNA has been fabricated by treating with polyvinyl alcohol (PVA) and used as a host for the laser dye Rhodamine 6G. The edge emitted spectrum clearly indicated the existence of laser modes and amplified spontaneous emission. Lasing was obtained by pumping with a frequency-doubled Nd:YA...
متن کاملTemperature-tunable lasing from dye-doped chiral microdroplets encapsulated in a thin polymeric film
In the last decade, much interest has grown around the possibility to use liquid-crystal droplets as optical microcavities and lasers. In particular, 3D laser emission from dye-doped cholesteric liquid crystals confined inside microdroplets paves the way for many applications in the field of sensors or tunable photonics. Several techniques can be used to obtain small microresonators as, for exa...
متن کاملFluorescent-Dye Doped Thin-Film Sensors for the Detection of Alcohol Vapors
Fluorescence sensors based on a trifluoroacetophone compound doped in ethyl cellulose (EC) thin films have been developed for the detection of methanol, ethanol, and 2-propanol (isopropanol, PriOH) vapors. Thin-film sensors are prepared with 4-dibutylamino-4’-(trifluoroacetyl)stilbene (Chromoionophore IX or CIX) as the fluorescent dye and its solution in EC was spin-coated onto glass slides. Th...
متن کاملOptical Reorientation in Dye-doped Liquid Crystals
The nonlinear optical properties of liquid crystals received considerable attention in the past decades and were reviewed by various authors. Harmonic generation in liquid crystalline phases and optical reorientation of nematics are examples of nonlinearities studied in detail. The present paper deals with the latter effect, paying special attention to the influence of absorption on the process...
