چکیده

     با استفاده از روش رسوب الکتروشیمیایی، لایه­های نازک سولفید قلع (SnS) خالص و آلایش یافته با ایندیوم از یک محلول آبی تهیه شدند. دمای حمام، زمان لایه­نشانی، پتانسیل انباشت لایه و pH به ترتیب ℃ 60، 30 دقیقه، V 1- و 1/2 بودند. لایه­های نازک تهیه شده با استفاده از روش­های پراش پرتو X (XRD)، میکروسکوپ الکترونی عبوری (FESEM)، نورتابناکی (PL) و طیف نگاری UV-vis مشخصه­یابی شدند. الگوهای XRD نشان دادند که آلایش ایندیوم، منجر به کاهش کیفیت بلوری و ریزتر شدن اندازه بلورها می­گردد. تصاویر FESEM نشان دادند که مورفولوژی لایه­های نازک دانه-شکل بوده و ساختارهایی در مقیاس میکرو/نانومتری وجود داشت. نتیجه آزمایش فوتولومینوساناس (PL) نشان داد که در اثر آلایش ایندیوم یک قله نشری جدیدی در محدوده نشر نور نارنجی ایجاد می­شود. آنالیز طیف نگاری UV-vis نشان داد که ویژگی جذب نور لایه­های نازک SnS پس از آلایش ایندیوم بهبود یافته و انرژی پهنای باند لایه­های SnS خالص از eV 45/1 به eV 40/1 کاهش یافت. بنابراین، کلیه نتایج نشان­دهنده نقش کلیدی آلاینده ایندیوم بر خواص ساختاری و نوری لایه­های نازک SnS است.

چکیده [English]

     Undoped and In-doped SnS thin films have been prepared using an electrochemical deposition method. The bath temperature, deposition time, deposition potential, and pH kept constant at 60 ℃, 30 minutes, -1 V and 2.1, respectively. The synthesized un- and In-doped SnS thin films have been characterized by X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), room temperature photoluminescence (PL), and UV-vis spectroscopy. The XRD patterns showed that the crystalline quality and crystallite size has been decreased after In-doping. The morphology of un-and In-doped SnS thin films was grain-like. A new PL emission peak has been appeared after In-doping. The absorbance spectra of In-doped SnS thin films have been improved, compared with that of undoped SnS. In addition, the band gap energy of undoped SnS is decreased from 1.5 eV to 1.45 eV due to In-doping. Therefore, all results showed that the key role of indium dopant on the structural and optical properties of SnS thin films.
