Organic whispering‐gallery mode lasers (OWGMLs), taking the advantages of organic
materials and whispering‐gallery mode (WGM) cavity, have undergone tremendous …

It is a generally accepted perspective that type-II nanocrystal quantum dots (QDs) have low
quantum yield due to the separation of the electron and hole wavefunctions. Recently, high …

Anticounterfeiting labels based on physical unclonable functions (PUFs) exhibit high
security with unreplicable code outputs, making them an ideal platform to realize …

Self‐assembled organic and polymer optical whispering‐gallery‐mode resonators
(WGMRs) are emerging as a potential alternative to traditional inorganic resonators. In the …

To improve the photophysical performance of colloidal quantum dots for laser applications,
sophisticated core/shell geometries have been developed. Typically, a wider bandgap …

Optical whispering gallery mode (WGM) microresonators have attracted great attention due
to their remarkable properties such as extremely high quality factor, small mode volume …

A series of luminescent frameworks was synthesized from the selective combination of
aggregation induced emission (AIE)‐linker tetra‐(4‐carboxylphenyl) ethylene (H4TCPE) …

Emerging CsPbX 3 (X= Cl, Br, and I) perovskite nanocrystals (NCs) have been
demonstrated to be efficient emitters with a high fluorescence quantum yield, making these …

Here, the first account of self-resonant fully colloidal μ-lasers made from colloidal quantum
