“…1(a). Since the growth pattern resembles that of their single coating counterparts [7,8], it could be assumed that no first hand interactions or bond formations happened between the two precursor types thereby retaining its intrinsic structural morphology. The films were continuous and without any large segregations which indicates a stable and efficient coating process.…”

“…3. The Q-band(700-950 nm) peak for vacuum deposited vanadyl and tin naphthalocyanine were reported to be around 814 nm and 845 nm respectively [7][8][9]. A composite thin film using these two materials could produce a broad Q-band spectrum.…”

“…They possess excellent thermal and chemical stability and are known for their strong near-infrared absorption, distinguishing them from other phthalocyanine dyes. These attractive features of naphthalocyanines dyes have been used to fabricate many modern organic electronic applications, such as electrochromic devices, optoelectronic materials, and organic photodiodes for photodynamic therapy (PDT) [12,[24][25][26][27][28][29][30][31][32][33][34][35][36][37][38]. Due to the absorption of SnNc around 875 nm, Melquíades et al [28] investigated the blend of SnNc and fullerene as an efficient NIRsensitive layer for fabricating an organic up-conversion device.…”

The spectroscopic and electronic properties of small-molecular organic semiconductors in thin films are a significant aspect that controls the performance of their optical/optoelectronic devices. A heterojunction of thermal vacuum deposited film of tin(II)2,3-naphthalocyanine (SnNC) dye onto a p-type Si wafer (SnNC/p-Si) was fabricated. The morphology of SnNC thin film onto Si wafer was explored using the Field Emission Scanning Electron Microscope (FE-SEM). The specular reflectance and the fluorescent properties of SnNC thin film onto Si wafer were investigated. The PL emission spectra of SnNC/p-Si emission bands are related to the B and Q absorption bands for SnNC. The spectral behavior of the refractive index and the specific polarizability for both SnNC/Glass and SnNC/p-Si were extracted. Under varying temperatures (298–378 K), the electronic properties of the SnNC/p-Si heterojunction were analyzed in dark conditions. The diode parameters of SnNC/p-Si heterojunctions were extracted from the current-voltage (I-V) procedure, which exhibited temperature-dependent behavior. According to the Cheung-Cheung and Norde procedure, the essential electrical diode parameters of the SnNC/p-Si device such as the ideality factor, the series resistance, and barrier height were estimated. The photoconductivity parameters such as the photocurrent, the sensitivity, and the responsivity of the SnNC/p-Si devices were estimated. We believe that these findings can be useful and utilized in optoelectronic and organic electronic applications.

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.
