| Inorganic semiconductor nanocrystals or quantum dots (QDs) show unique and size specific optical, photoluminescence (PL) and electronic properties, which make them very promising and demanding material for diverse applications. However, majority of QDs are susceptible towards surface oxidation when exposed to air, which modifies their functional behavior (e.g., PL quenching) and renders it useless for developing applications. Hence, synthesis, functionalization and fabrication of good quality QDs are performed under controlled inert atmosphere, which requires specific laboratory facilities, rendering it scientifically a tedious field and making it costsensitive. This review article focuses on recent developments in chemical synthesis and surface modification strategies for different QDs to make them stable under ambient conditions without compromising their opto-electronic properties. This article also includes the strategies adopted to regenerate the PL properties of already surface oxidized QDs. |
