Abstract

We propose a full optical method for gas sensing by few-layer MoS2 nanosheets
obtained by liquid-phase epitaxy (LPE). Our samples are fully characterized by
transmission electron microscopy (TEM), photoluminescent (PL) spectroscopy, and Xray
diffraction (XRD). Further characterization and evaluation of gas sensing
application, had been done by implementing ultraviolet-visible spectroscopy (UV/Vis).
For CO2 gas which acts as a donor to our sample (based on the evaluation method that
used in this work), we calculate the response in the visible region equal to 15% while
in longer wavelengths (near-infrared) the response clearly decreased. Our experiments
show that using 2D transitional metal dichalcogenide (TMDC) materials for Gas
sensing applications may open a new horizon for using this kind of 2D material in
various types of optical sensors.

Abstract [Persian]

ما یک روش نوری کامل برای سنجش گاز توسط نانوذرات لایه ای مولیبدن دی سولفید که توسط لایه سازی فازی توسط محلول به دست آمده را ارائه می دهیم. نمونه ما به طور کامل با میکروسکوپ الکترونی عبوری، طیف سنجی فوتولومینسانس و پراش پرتونگاری اشعه ی ایکس مشخصه یابی می شود. توصیف بیشتر و ارزیابی کاربرد سنجش گاز ورقه های مولیبدن دی سولفید، با انجام طیف سنجی اشعه ماوراء بنفش و مرئی انجام شده است. برای ارزیابی خواص حسگری نمونه از گاز کربن دی اکسید استفاده شده است، ما پاسخ را در منطقه مرئی با 15٪ افزایش مشاهده می کنیم و اما در طول موجهای بالاتر (نزدیک مادون قرمز) این مقدار شدیدا کاهش پیدا میکند. آزمایشات ما نشان می دهد که استفاده از مواد دو بعدی دی کالکوژن فلزات واسطه برای کاربردهای سنجش گاز ممکن است افق جدیدی را برای استفاده از این نوع مواد در انواع حسگرهای نوری باز کند.
