The term “Nanocrystal Engineering” can be defined as the design and synthesis of
nanocrystals with desired morphologies and compositions based on understanding and …

By taking advantage of well-defined spectroscopic signatures of high-quality CdSe/CdS
core/shell QDs, the effects of oxygen on photoluminescence (PL) of QDs were studied …

A Highly ordered CdS nanoflake array was fabricated by CVD, and its gas sensing
characteristics were investigated. The sensor exhibited high response (resistance ratio) of …

Implementing sensitive and fast ppb-level formaldehyde sensing at room temperature is still
in extreme demand for practical indoor air quality monitoring. Herein, we developed a visible …

Solution-processed SnO2 colloidal quantum dots (CQDs) have emerged as an important
new class of gas-sensing materials due to their potential for low-cost and high-throughput …

Colloidal quantum wells combine the advantages of size-tunable electronic properties with
vast reactive surfaces that could allow one to realize highly emissive luminescent-sensing …

MgO entangled nanosheets (MgOENS) with unique vertically-oriented morphology were
produced via anodization and functionalized with CdS nanoparticles (NPs). Structural and …

X-ray photoemission spectroscopy (XPS) has been used to examine the interaction between
Au and HfS3 at the Au/HfS3 interface. XPS measurements reveal dissociative chemisorption …

We have fabricated UV-sensitive photodetectors based on colloidal CdS nanocrystals and
graphene. The nanocrystals act as a sensitizer layer that improves light harvesting leading …

The structural interpenetration in metal–organic frameworks impacts the porosity
designability and tunability of photon absorption; however rationally modifying the functions …
