چکیده

در این مقاله، نانوصفحات هیدروکسید منیزیم با خلوص بالا توسط روش رسوب‌دهی‌تر با استفاده از شورابه غنی از یون‌های منیزیم به‌عنوان پیش‌ماده و NaOH به‌عنوان عامل رسوب‌دهی بدون استفاده از عامل پراکنده‌ساز در دمای اتاق با موفقیت سنتز شد. مشخصه‌یابی و بررسی خصوصیات مختلف نانوپودر به‌دست‌ آمده توسط آزمون پراش پرتو ایکس، میکروسکوپی الکترونی روبشی گسیل میدانی، طیف سنجی انرژی پرتوایکس، طیف سنجی مادون قرمز و طیف جذبی انجام شد. نتایج آزمون پراش پرتو ایکس و میکروسکوپی الکترونی روبشی گسیل میدانی نشان داد که پودر هیدروکسید منیزیم دارای نانوصفحاتی با میانگین اندازه کریستالیت 1/17 نانومتر و فاقد هرگونه ناخالصی است؛ که با نتایج طیف سنجی انرژی پرتوایکس و طیف سنجی مادون قرمز کاملاً در توافق بود. علاوه بر این، بررسی خصوصیات نوری نانوصفحات هیدروکسید منیزیم توسط طیف‌سنجی UV-Vis، یک گاف نواری نوری 5/5 الکترون ‌ولت را نشان داد. این گاف نواری پهن می‌تواند نوآوری مفید در وسایل نوری- الکترونیکی زیرمیکرون باشد.

چکیده [English]

In this paper, high purity magnesium hydroxide nanoplates were successfully synthesized by using brine rich in magnesium ions as precursor and NaOH as precipitating agent without using dispersant agent in the room temoerature. The study and characterization of various properties of obtained nanopowder was carried out by X-Ray Diffraction (XRD), Field Emission Scanning Electron Microscopy (FESEM), Energy Dispersive X-ray Fluorescence Spectrometer (EDX), Fourier Transform Infrared Spectrophotometer (FTIR) and Ultraviolet–visible spectroscopy (UV-Vis). The FESEM and XRD analysis results showed that magnesium hydroxide powder had nanoplates with the average crystallite size 17.1nm and no impurity; that was in agreement with the result of EDX and FTIR perfectly. Furthermore, optical characteristics of magnesium hydroxide nanoplates by UV-Vis spectroscopy showed an optical band gap of 5.5 eV. This wide band gap can be a useful innovation in optoelectronic sub-micron devices.
