چکیده

این پژوهش بر تاثیر آلاییدگی کادمیم در شبکه بلوری لایه نانوالیافی اکسید قلع (IV) تمرکز کرده است. لایه نانوالیافی با استفاده از روش الکتروریسی تهیه گردید که بدون مهره و دارای سطح مقطع دایره­ای بودند. آثار آلاییدن با کادمیم این نانوالیاف بر روی شبکه بلوری با استفاده از الگوهای پراش پرتو ایکس مورد مطالعه قرار گرفت. مقادیر پارامترهای شبکه اکسید قلع (IV) و به نوبه خود حجم سلول واحد و چگالی آن، بسیار کم افزایش پیدا کرده است. این تغییر را می­توان به ورود کادمیم به ساختار بلوری اکسید قلع (IV) ارتباط داد. البته آلاییدن با کادمیم تاثیری بر روی زوایای سلول واحد نگذاشته است و همان ساختار تتراگونال حفظ گردیده است. باید گفته شود که قلّه­ها کمی به سمت زوایای بزرگ­تر جا به جا شد که به تشکیل تهی‌جا در مکان آنیون­ها (اکسیژن) نسبت داده شد.

چکیده [English]

This research focuses on the effect of cadmium doping on the crystal lattice of the tin oxide (IV) nanofibrous layer. This nanofibrous layer was prepared using the electrospinning method which had no beads and had a circular cross-section. The effects of cadmium doping of these nanofibers on the crystal lattice were studied using X-ray diffraction patterns. The values of tin oxide (IV) lattice parameters and in turn, the unit cells volume and its density increased very little. This change can be related to the entry of cadmium into the crystal structure of tin oxide (IV). However, doping with cadmium had no effect on unit cell angles and the same tetragonal structure was preserved. It should be noted that the peaks shifted slightly toward larger angles which were attributed to the formation of voids at the location of anions (oxygen).
