Structure, optical, and surface characteristics of irradiated PEO/Gd2O3 for optoelectronics
Source abstract
Abstract
In this work, the polyethylene oxide (PEO) polymer and nanofiller gadolinium oxide (Gd2O3) are combined to produce the composite (PEO/Gd2O3) for application in optical materials with high flexibility. The composites were successfully fabricated using the solution-casting preparation method and characterized by using X-ray diffraction and scanning electron microscope techniques. Then, the samples were irradiated by the cold cathode ion source with hydrogen (H+) ion fluence of 3 × 1017, 6 × 1017, and 9 × 1017 ions/cm2. The ultraviolet–visible method is used to study the optical behaviour of the irradiated composite in frequency range of 200–1100 nm. The dispersion energy changed from 1.62 eV for PEO/Gd2O3 to 1.60, 1.58, and 1.54 eV for the irradiated films by 3 × 1017, 6 × 1017, and 9 × 1017 ions/cm2, respectively. In addition, the oscillation energy EO changed from 6.93 eV for PEO/Gd2O3 to 6.19, 6.61, and 6.54 eV, respectively. These modifications of the irradiated films result from a combination of the amorphization, defect formation, and polymer–nanoparticle interactions, making the irradiated PEO/Gd2O3 nanocomposite more suitable for optoelectronics devices.
