The partially reversible photochromic behavior of Ag-0 nanoparticle incorporated titanosilicate ETS-10 films was achieved for the first time. Ag+ ions were incorporated into ETS-10 matrix by ion-exchange of extra framework cations (i.e., Na+ and K+) to form Ag+ ion-exchanged ETS-10. The colored (i.e., activated state) and colorless (i.e., bleached state) forms of the photochromic system of Ag-0 nanoparticle incorporated ETS-10 films were achieved through thermal reduction and exposure to visible laser at 532 nm wavelength, respectively. The resulting Ag-0-ETS-10 films and also Ag+-ETS-10 crystals have been characterized by ICP-OES, XRD, XPS, FE-SEM, HR-TEM, UV-vis spectroscopies. Partial restoration of color was achieved after second thermal treatment, which implies reversibility of the photochromic process. Furthermore, Density Functional Theory (DFT) results showed that ETS-10 had robust geometry and incorporation of the silver nanoparticles had minimal effect on the structure. The relationship of ETS-10's unique structural formation along with the integration of Ag-0 nanoparticles within its matrix and its subsequent photochromic property was shown for the first time.

Microporous vanadosilicate films with tailorable V4+/V5+ ratio to achieve enhanced visible-light photocatalysis Kuzyaka, Duygu; Uzun, Ceren; Yıldız, İlker; Kaya, Murat; Akata Kurç, Burcu (2021-08-01) This study investigates the changes induced into the photocatalytic activity under solar light irradiation upon changing the structural film properties and tailor the concentration of defects in microporous vanadosilicate AM-6 films. For this purpose, the preparation of AM-6 films with different V4+/V5+ ratios and their utilization as photocatalysts for the decomposition of MB were carried out. Two approaches were used for obtaining AM-6 films with different V4+/V5+ ratios: altering the seed layer coating t...
Enhanced Optical Absorption and Spectral Photocurrent in a-Si:H by Single- and Double-Layer Silver Plasmonic Interfaces Saleh, Zaki M.; NASSER, Hisham; ÖZKOL, Engin; GÜNÖVEN, Mete; ALTUNTAS, Burcu; Bek, Alpan; Turan, Raşit (2014-04-01) Single and double plasmonic interfaces consisting of silver nanoparticles embedded in media with different dielectric constants including SiO2, SiNx, and Al:ZnO have been fabricated by a self-assembled dewetting technique and integrated to amorphous silicon films. Single plasmonic interfaces exhibit plasmonic resonances whose frequency is red-shifted with increasing particle size and with the thickness of a dielectric spacer layer. Double plasmonic interfaces consisting of two different particle sizes exhib...
Adhesion of an HTPB-IPDI-based liner elastomer to composite matrix and metal case Haska, SB; Bayramli, E; Pekel, F; Özkar, Saim (1997-06-20) Adhesional characteristics of an elastomeric liner composition toward a highly filled composite matrix and metal case were investigated. The system is composed of an excess isocyanate functionality in the elastomer compared to an excess hydroxyl functionality in the composite matrix. Both phases essentially contain the same binder (HTPB) and curing agent (IPDI). A bifunctional aziridine (MAPO) is used as a bond (adhesion) promoter. The effects of the R value, triol/diol ratio, and MAPO concentration on the ...
Electroformed silicon nitride based light emitting memory device ANUTGAN, TAMİLA; ANUTGAN, MUSTAFA; ATILGAN, İSMAİL; Katircioglu, Bayram (2017-07-31) The resistive memory switching effect of an electroformed nanocrystal silicon nitride thin film light emitting diode (LED) is demonstrated. For this purpose, current-voltage (I-V) characteristics of the diode were systematically scanned, paying particular attention to the sequence of the measurements. It was found that when the voltage polarity was changed from reverse to forward, the previously measured reverse I-V behavior was remembered until some critical forward bias voltage. Beyond this critical volta...
Si nanocrystals in sic matrix and infrared spectroscopy of in a dielecric matrix Gencer İmer, Arife; Turan, Raşit; Department of Physics (2010) This study focuses on various aspects of nanocrystals embedded in a dielectric matrix. In the first part of this work, a new approach with the use of Fourier Transform Infrared spectroscopy (FTIR) in the nanocrystal analysis was developed and presented. Si and Ge nanocrystals embedded in SiO2 matrix were mainly studied. This new approach is based on the analysis of structural variations of SiO2 matrix during the formation of semiconductor nanocrystlas. It is shown that the chemical and structural variations...
