Ishda CsPbBr₃ kvant nuqtalarining ZnO va TiO₂ oksid yarimo‘tkazgichlari bilan hosil qilgan heterointerfeyslarida fotoqo‘zg‘algan zaryad tashuvchilar dinamikasi qiyosiy tahlil qilindi. Tahlilning asosiy mezonlari sifatida energetik zonalar moslashuvi, interfeysdagi zaryad qayta taqsimlanishi, fotoluminessensiya (PL) so‘nishi va vaqt bo‘yicha ajratilgan fotoluminessensiya (TRPL) ko‘rsatkichlari tanlandi. CsPbBr₃/ZnO tizimida elektron ekstraksiyasi va issiq tashuvchilar kinetikasi, CsPbBr₃/TiO₂ tizimida esa ichki elektr maydon bilan boshqariladigan S-sxemali zaryad transferi asosiy mexanizmlar sifatida qaraldi. Natijalar PL intensivligining o‘zgarishini alohida ko‘rsatkich sifatida emas, balki rekombinatsiya tezligi, sirt nuqsonlari va interfeys morfologiyasi bilan birgalikda talqin qilish zarurligini ko‘rsatadi. Shu asosda ZnO va TiO₂ ning CsPbBr₃ optik javobiga ta’sirini ajratib beruvchi eksperimental tekshiruv sxemasi taklif qilindi.
