A comprehensive review on LED-induced fluorescence in diagnostic pathology

Lead-free hybrid indium perovskites with near-unity PLQY and white light emission using an Sb3+doping strategy

“…Luminescent materials are widely used in energy information, medical technology, sensors, and light-emitting diodes (LEDs). [1][2][3] In recent years, various types of luminescent materials, such as organic polymer emitters, metal complexes, rare earth oxide phosphors, and hybrid OIMHs, [4][5][6][7] have been extensively explored. Among them, organic-inorganic hybrid metal lead halide perovskites have become a strong competitor for various luminescent materials due to their excellent optoelectronic properties.…”

Integrated LED-induced fluorescence correlation spectroscopy module for lucigenin concentration detection

“…Light-emitting diodes (LEDs), which have various good advantages, including being extremely compact, cost-effective, energy-efficient, and power stable, have the potential to further improve the FCS system integration level. LEDs are semiconductor-based light sources in which the bandgap (eV) affects the energy and wavelength of the light emitted, which may suit the excitation criteria of most fluorescent molecules [13]. For example, LEDs have been used as an excitation light source in developing absorption, fluorescence, and reflection spectroscopy-based optic-analytical instruments [14][15][16][17] for various analytical application.…”

“…Our FCS architecture is an elaborate module composed of optics, mechanism, electricity and calculation, and its size (65mm×55mm×35mm) is only the 4/5 of a campus card. LED is used as the excitation source in the FCS module, which has various performance advantages over lasers[13]:(i) Abundant excitation wavelength selection: the range of commercially available LEDs' central wavelengths, from 255 to 4600 nm.…”
