We present the results concerning the excitation and emissions spectra of Poly (N-carbazole) (PVK) blended with poly(vinylidene uoride-co-hexauoropropene), (PVDF-HfP) and polyvinylpyrrolidone (PVP). Thin lms of PVK blended with PVDF-HfP (PVK:PVDF-HfP) and PVP (PVK:PVP) were prepared using doctor blade technique on spectrosil substrate. The inuences of polymer blends on the excitation and emission spectra were observed under UV excitation source of a xenon lamp. The result shows a discrepancy in the maximum excitation and emission for each sample. The possible energy transfer and recombination mechanisms have been related with singlet-singlet semi-empirical INDO electronic calculation and FTIR measurements.

“…It is also observed that the value of the refractive index increases with the increase of MoO3 concentration especially at low wavelength region. This type of composite film has a high refractive index which makes it possible to use it in wave guide technology, antireflective coating and photonic devices [25]. 5.…”

Polyvinyl alcohol-molybdenum oxide (PVA-MoO3) composite films were prepared by solution casting technique. The weight percentages of the oxide in the films were 2.5% and 5%. The films were characterized by using a computerized double beam UV-VIS spectrophotometer. Optical parameters of the composite films such as real (n) and imaginary (k) parts of refractive index, optical conductivity and dielectric constant were calculated. Other optical parameters (the oscillator energy (E0) and dispersion energy (Ed)) have been also evaluated. The obtained results revealed that doping of MoO3 had a significant effect on the optical properties. The results showed that the increased ratio of the oxide led to an increase in the calculated values of the PVA film parameters and shifted toward high wavelength. The addition of 5.0% of MoO3 to PVA film raised the refractive index (n) value by 38.5%. The Results of this study show that the PVA-MoO3 film can have many applications, especially in the area of antireflective coating and photonic devices.

“…There are many benefits of polymers, for example, low cost, fast treatment, durability, strong high strength and mechanical properties. They are used in the photolithography process in the microelectronic fabrication industry [18][19][20]. Polymeric nanocomposites consisting of inorganic nanoparticles and organic polymers constitute a class of materials, which, in recent years, have created considerable interest [21].…”
