“…The PTCDI-C5 molecule has two absorption maxima like in the Soret (B) and Q bands in the literature. [52,61,64,66] The so-called Q-band is comparatively low and occurs in the visible (V) region and at lower photon energies. [84] In the visible region (from 1.59 to 3.26 eV), there are five Figure 2.…”

Investigation of the spectral, optical and surface morphology properties of the N,N′-Dipentyl-3,4,9,10-perylenedicarboximide small molecule for optoelectronic applications † Bayram Gündüz* The spectral and optical properties of the solutions of the N,N′-Dipentyl-3,4,9,10-perylenedicarboximide (PTCDI-C5) small molecule for different molarities were investigated in detail. The significant spectral parameters such as molar/mass extinction coefficients, absorption coefficient, electric dipole line strength, and oscillator strength of the PTCDI-C5 molecule were calculated. The absorption bands of PTCDI-C5 show vibronic structures with seven peaks at 2.08, 2.35, 2.53, 2.70, 2.86, 3.32, and 3.86 eV, respectively. The electronic spectra of the PTCDI-C5 can be characterized by two basic regions as visible and Soret band. Effects of the molarities on the significant many optical parameters were investigated in detail. The direct and indirect allowed optical band gaps of the PTCDI-C5 decrease with increasing molarity. Then, surface morphology properties were investigated and calculated roughness parameters of the PTCDI-C5 film. Finally, we discussed for optoelectronic applications of these parameters, and this study was compared with the similar and related studies in the literature.

“…In 2008, Chu and Lo [20] described the highly-sensitive ratiometric fiber-optic oxygen sensors incorporating a sol-gel matrix doped with PtTFPP or PdTFPP metalloporphyrins as oxygen-sensitive material and 7-amino-4-trifluoromethyl coumarin (AFC) as the reference dye. The resulting oxygen sensor was of good linearity in the Stern-volmer plot calibration (Fig.…”

Oxygen and carbon dioxide sensors are involved in many chemical and biochemical reactions. Consequently, considerable efforts over years have been devoted to discover and improve suitable techniques for measuring gas concentrations by optical fiber sensors. Optical gas sensors consist of a gas-sensitive dye entrapped in a matrix with a high permeability to gas. With such sensors, gas concentration is evaluated based upon the reduction in luminescence intensity caused by gas quenching of the emitting state. However, the luminescence quenching effect of oxygen is highly sensitive to temperature. Thus, a simple, low-cost plastic optical fiber sensor for dual sensing of temperature and oxygen is presented. Also, a modified Stern-Volmer model is introduced to compensate for the temperature drift while the temperature is obtained by above dual sensor. Recently, we presented highly-sensitive oxygen and dissolved oxygen sensors comprising an optical fiber coated at one end with platinum (II) meso-tetrakis(pentafluorophenyl)porphyrin (PtTFPP) and PtTFPP entrapped core-shell silica nanoparticles embedded in an n-octyltriethoxysilane(Octyl-triEOS)/tetraethylorthosilane (TEOS) composite xerogel. Also, two-dimensional gas measurement for the distribution of chemical parameters in non-homogeneous samples is developed and is of interest in medical and biological researches.
