Past haroratli usulda rux oksid nanotuziilmalarini tayyorlash va ularning fotoluminessensiya xossalarini o‘rganish4o
Annotatsiya
ZnO nanorodlari past haroratli gidrotermal usul orqali zanglamaydigan po‘lat simlardan to‘qilgan panjara ustida muvaffaqiyatli sintez qilindi. Bizning usulimiz oddiy botirish-qoplash texnikasi orqali urug‘lantirish jarayoni, undan keyin esa issiqlikda pishirish va ZnO nanotuziilmalarini gidrotermal o‘stirish bosqichlarini o‘z ichiga oladi. Nanorodlar ikkinchi marta sintez qilinganda, ularning o‘lchami oshdi va fotoluminessensiya spektrining maksimumi uzunroq to‘lqin uzunligiga siljidi. PL nurlanish diapazonining siljishi nanotuziilmalarning o‘lchamining oshishi bilan bog‘liqligi kuzatildi. Shu bilan birga, namunalar fotoluminessensiya spektrlari nuqsonlar bilan bog‘liq nurlanish diapazonining kuchayganini ko‘rsatdi. PL spektrida kuzatilgan nuqsonlar oraliq kislorod deb hisoblanganda, ushbu nuqsonga mos keluvchi nurlanish diapazonining ikki marta sintez qilingan namunalarda kuchaygani bu nuqsonlarning hajmiy (bulk) xususiyatga ega ekanligidan dalolat beradi.
