Copper oxide formation has been investigated to combine the advantages of producing different size and shapes of coatings that possess good light absorbing properties. An aqueous blackening solution was investigated and optimum composition was found as 2.5 M NaOH and 0.225 M NaClO to form velvet copper oxide films. A two-step oxidation mechanism was proposed for the blackening process by carefully examining the experimental results. Formation of Cu2O was observed until the entire copper surface was covered at first. In the second step, Cu2O surface was further oxidized to CuO until the whole Cu2O surface was covered by CuO. Therefore, blackened copper surfaces consisted of Cu2O/CuO duplex oxides. Characterization of the coatings were performed in terms of microstructure, phase analysis, chemical state, infrared specular and total reflectivity by SEM, XRD, XPS, FUR and UV-vis spectrophotometry, respectively.

Enhancement of Physical and Mechanical Properties of Epoxy Resins by Graphene/Graphene Oxide Additives
Budak, Deniz; Yıldırım, Erol; Department of Polymer Science and Technology (2022-1-23)
Control of interfacial interactions is essential for the preparation of polymer matrix composites with enhanced physical, mechanical, thermal and electrical properties. The performance of the graphene and graphene oxide (GO) additives can be improved by achieving strong adhesion and uniform dispersion of GO in the epoxy matrix. In this study, modeling and simulation of DGEBA (Bisphenol A diglycidyl ether)/DETA (Diethylenetriamine) based epoxy nanocomposites containing graphene and graphene oxide (GO) additi...
Atomic layer deposited Al2O3 passivation of type II InAs/GaSb superlattice photodetectors
Salihoglu, Omer; Muti, Abdullah; Kutluer, Kutlu; Tansel, Tunay; Turan, Raşit; Kocabas, Coskun; Aydinli, Atilla (AIP Publishing, 2012-4)
Taking advantage of the favorable Gibbs free energies, atomic layer deposited (ALD) aluminum oxide (Al2O3) was used as a novel approach for passivation of type II InAs/GaSb superlattice (SL) midwave infrared (MWIR) single pixel photodetectors in a self cleaning process (lambda(cut-off) similar to 5.1 mu m). Al2O3 passivated and unpassivated diodes were compared for their electrical and optical performances. For passivated diodes, the dark current density was improved by an order of magnitude at 77 K. The ze...
Preparation and characterization of cost effective spray pyrolyzed absorber layer for thin film solar cells
Sankir, Nurdan D.; Aydin, Erkan; Unver, Hulya; Uluer, Ezgi; Parlak, Mehmet (Elsevier BV, 2013-09-01)
In this study, highly (1 1 2) oriented crystalline copper indium disulfide (CuInS2) thin films with high mobility have been deposited via ultrasonic spray pyrolysis. Structural and electrical properties of CuInS2 thin films were examined to utilize them in solar cell applications. Various amounts of precursor solution ranging from 0.25 to 2.02 ml/cm(2) were used to form CuInS2 thin films onto the soda lime glass substrates. Scanning electron microscopy (SEM) analysis revealed that all sprayed films were pin...
Synthesis and Characterization of Aluminum Containing Silica Aerogel Catalysts for Degradation of PLA
Sivri, Seda; Dilek Hacıhabiboğlu, Çerağ; Sezgi, Naime Aslı (Walter de Gruyter GmbH, 2019-05-01)
Aluminum loaded silica aerogel based catalysts were synthesized by impregnation of aluminum into silica aerogel produced using sol-gel method in different aluminum loadings (2.5-15 wt%) to investigate their performances in degradation of polylactic acid (PLA).
Formation of gold plated electroformed copper structures
Arslan, Burcu; Karakaya, İshak (2016-01-01)
Gold-plated electroformed copper structures are used to protect sensors from stray radiation and improve the image quality in infrared cameras, imaging systems, missile guidance systems and several other devices. These multilayer electroformed objects have tight dimensional and weight tolerances. Furthermore, their internal and external surfaces often exhibit low and high emissivity, respectively. Reflectivity at the outer surface was achieved by gold electrodeposition. Moreover, inner copper layer was conv...
