Investigation on Zinc Selenide and Copper Selenide Thin Films Produced by Chemical Bath Deposition

Abstract

The zinc selenide and copper selenide thin lms were deposited by chemical deposition technique on glass substrates. For both lms, sodium selenosulphate was used as a selenide ion source in an alkaline solution. The X-ray diraction patterns show that the ZnSe has a cubic structure and Cu3Se2 lm has a tetragonal structure. The relative intensity K β /Kα of zinc and copper selenide thin lms has been measured by using a 241 Am radioisotope source (75 mCi). The obtained results were compared with the theoretical values.

Bakır oksit ince filmlere bor katkısının metil mavisi üzerindeki fotokatalitik etkisinin araştırılması

“…Filmlerin fotokatalitik verimliliklerinin yüksek olduğunu gördüler ve boyar maddelerin 90 dakika içinde tamamen bozunmasına yol açtığını belirlediler [15]. Bakır tabanlı ince filmleri üretmek için; sprey piroliz tekniği, spin kaplama, daldırmalı kaplama, termal buharlaştırma, kimyasal buhar biriktirme, sol-jel, kimyasal banyo yöntemi gibi çeşitli teknikler kullanılmıştır [1,[20][21][22][23][24][25]. Nano yapılı bakır oksit parçacık üretmek için birçok yöntem bulunmasına rağmen, çoğu zaman alıcıdır ve oldukça maliyetlidir [26].…”

Variation of Cathodic voltages and their effect on Optical Properties and Conductivity Type of Electrodeposited Aluminium Selenide Thin Films for Optoelectronic Applications

“…Since compound semiconductor has more functionalities than elemental semiconductor, compound semiconductors such as cadmium telluride, zinc oxide, zinc sulphide, lead sulphide etc., are therefore received scientific attention. We chose to form aluminium selenide because of the potential of selenium in compound semiconductors such as zinc selenide, copper selenide (Durdua et al, 2013), lead selenide (Ezenwa, 2012) etc. The band gap of Al2Se3 has been reported as 3.1 eV at wavelength of 401 nm which make it possible to be potentially used in photoemitter (Mansoor & Yilbas, 2018;Beck & Funk, 2012).…”

Enhanced Band Gap Energy and Electrochromic Behaviour of Selenium Incorporated Copper Thin Film

“…[6][7][8][9] Thin films of CuSe are normally crystallised in hexagonal structure and orthorhombic structure. Numerous techniques have been used to obtain CuSe thin films viz., thermal evaporation, 10 vacuum evaporation, 11 solution growth technique, [6][7][8][9][10][11][12] chemical bath deposition, [13][14][15][16][17][18][19] colloidal hot injection method, 20 vapour deposition, 21 and electrophoretic deposition. 22 Among them, electrodeposition technique provides many advantages over vacuum and other processes, such as low temperature growth, control of film thickness and morphology, potentially low capital cost 1,23 and others.…”
