“…Also, the molecular structure and optoelectronic characteristics can be simply modified to improve charge transport, radiative recombination, or photogeneration depending on the needed pioneer technological optoelectronic applications [1][2][3][4][5][6][7][8][9][10][11]. Due to the excellence of phthalocyanines as electronic and optical materials, experimentalists and computational researchers have explored their structural, optical, electrical, and optoelectronic properties in excessive detail [12][13][14][15][16][17][18][19][20][21][22]. Naphthalocyanines are planar π-extended phthalocyanine derivatives with good chemical and thermal stability.…”

Herein, tin(II) 2,3-naphthalocyanine (SnNC) organic dye was successfully thermally deposited onto different optical transparent substrates such as glass, quartz, ITO, and FTO. FE-SEM technique reveals that SnNC film shows a uniform and symmetrical spherical-shaped with an average diameter of ∼50 nm. Annealing up to 473 K for 4 h increases the crystallite size of SnNC thin film. SnNC thin film shows absorption bands centered at 858 nm, 313 nm, and 249 nm with two shoulders at 775 nm and 350 nm. We present the absorbance, specular transmittance, specular reflectance and fluorescence properties of SnNc deposited on the different transparent substrates. The oscillator strengths (f) and the electric dipole strength (q2) of SnNC thin film were estimated from the molar absorptivity ( ε molar ) spectra. According to the Tauc model, two optical gap transitions were estimated as 1.03 eV and 3.48 eV. Annealing up to 473 K for 4 h slightly increases them to 1.15 eV and 3.59 eV, respectively. At excitation wavelength = 360 nm, two emission bands were observed at around 403 nm and 674 nm. Upon annealing at 373 K and 473 K, the real part of the refractive index of SnNC thin film decreases, which is correlated with a decrease in mass density. Electrochemical HOMO—LUMO band gaps of SnNC estimated from the cyclic voltammetry (CV) measurements ( E g C V = 1.12 eV ) agree well with the observed optical energy gap estimated from the optical measurements. The wide range absorption, emission, good thermal stability, suitable optical band gap, and electrochemical properties, prove an effective example of organic dye suitable for organic electronic applications.

In this study, different experimental conditions is used to investigate the physical characteristics of new 4-Tetra-4-Tolyl-Sulfonyl: Iron-Phthalocyanine (4T4TS-FePc) thin films. The structural, morphological, and optical properties of 4T4TS-FePc thin films were then determined using a range of results. The majority of the material's properties indicate to its ingrained tendency to act as a photocatalyst, which is supported by the speed at which MB degrades under ultraviolet-visible light and may be suitable for applications aimed at wastewater treatment.

The beamline optics and endstations at branch B of the Versatile Soft X-ray (VerSoX) beamline B07 at Diamond Light Source are described. B07-B provides medium-flux X-rays in the range 45–2200 eV from a bending magnet source, giving access to local electronic structure for atoms of all elements from Li to Y. It has an endstation for high-throughput X-ray photoelectron spectroscopy (XPS) and near-edge X-ray absorption fine-structure (NEXAFS) measurements under ultrahigh-vacuum (UHV) conditions. B07-B has a second endstation dedicated to NEXAFS at pressures from UHV to ambient pressure (1 atm). The combination of these endstations permits studies of a wide range of interfaces and materials. The beamline and endstation designs are discussed in detail, as well as their performance and the commissioning process.
