CAS Number 15243-48-8
Perovskite quantum dots (CAS number 15243-48-8) are semiconducting nanocrystals. Compared to metal chalcogenide quantum dots, perovskite quantum dots are more tolerant to defects and have excellent photoluminescence quantum yields and high colour purity. These properties are highly desirable for electronic and optoelectronic applications and hence perovskite quantum dots have huge potential for real world applications including LED displays and quantum dot solar cells.
Caesium lead bromide (CsPbBr3) perovskite quantum dots powder is readily soluble in hexane, octane, and toluene.
