چکیده
حسگر گاز H2S با رشد نانومیله­های SnO2 بر یک بستر بهم پیوسته نقره و پوشش چرخشی نانوذرات SnO2 در سطح نانو میله­ها ساخته شد. هندسه، ریخت­شناسی، ترکیب شیمیایی، ویژگی نوری و الکتریکی با استفاده از میکروسکوپ الکترونی روبشی انتشار میدان (FESEM)، طیف­سنجی پرتو ایکس پراکندگی انرژی (EDAX)، پراش پرتو نگاری با پرتو ایکس، طیف­سنجی نور پایه و طیف­سنجی جذب مورد بررسی قرار گرفت. حسگر ساختگی با آلایش نانوذرات SnO2 با نقره و همچنین، با استفاده از روش نوآورانه قرار گرفتن همزمان در معرض پرتو فرابنفش و تعادل الکتریکی (خود گرمایش) تقویت شد. اقدامات ما منجر به تولید یک حسگر بسیار حساس با گستره تشخیص بسیار کم  (500 ppb تا 10 ppm ) شد که در آن برای نخستین بار از تداخل گاز H2O نیز در سنجش گاز استفاده  شد. با توجه به این دستاورد زمان پاسخ حسگر و زمان بهبودی در 10 ppm گاز H2S بطور قابل توجهی به ترتیب از 10 و 11 ثانیه شیوه اولیه به 5 و 8 ثانیه از شیوه اصلاح شده رشد یافته است. حساسیت متقابل حسگر نسبت به C6H6, C2H5OH, CO2و NH3نیز به منظور تعیین انتخابی حسگر مورد بررسی قرار گرفت.
