Afterglow materials are attracting widespread attention owing to their distinctive and long-
lived optical emission properties which create exciting opportunities in various fields. Recent …

Organic light-emitting diodes (OLEDs) have become popular displays from small screens of
wearables to large screens of televisions. In those active-matrix OLED displays …

Triplet excitons usually do not emit light under ambient conditions due to the spin-forbidden
transition rule, thus they are called dark excitons. Herein, triplet excitons in carbon nanodots …

Due to the non-radiative decay of excited states, it is extremely complicated for iridium (III)
complexes to simultaneously harvest high-efficiency and long-wavelength emission in the …

A class of four bright heterobimetallic emitters is presented, which features both a
chromophoric [Ir (C^ N) 2] center and a positively charged, linear bis-NHC M (I) ancillary …

Photoactive chromium (III) complexes saw a conceptual breakthrough with the discovery of
the prototypical molecular ruby mer-[Cr (ddpd) 2] 3+(ddpd= N, N′-dimethyl-N, N′-dipyridin …

The use of photocatalytic systems involving semiconductor materials for environmental and
energy applications, such as water remediation and clean energy production, is highly …

Traditional indirect flat-panel X-ray imaging (FPXI) uses inorganic scintillators with high-Z
elements, which lack spectral information about X-ray photons and reflect only integrated X …

Photodynamic therapy (PDT) has emerged as an efficient and noninvasive treatment
approach utilizing laser-triggered photosensitizers for combating cancer. Within this rapidly …

The development of future quantum devices such as the maser, ie, the microwave analog of
