Nanostructured organosilicon luminophores for efficient and fast elementary particles photodetectors

摘要

Nanostructured organosilicon luminophores (NOLs) consist of two types of covalently bonded via silicon atoms organic luminophores with efficient Forster resonance energy transfer (FRET) between them. Such molecular structure allows NOLs to combine the best properties of organic luminophores and inorganic quantum dots: high absorption cross-section and photoluminescence quantum yield, large pseudo-Stokes shift, fast luminescence decay time, good solubility and processability. Thin films of NOLs or their composites with optical plastics are transparent, which leads to efficient and fast conversion of UV into visible light in different types of photodetectors and other optoelectronic devices. This paper briefly reviews recent advances in the application of NOLs as wavelength shifters (WLS) in various types of elementary particles photodetectors: liquid xenon detectors with PMT and silicon photomultipliers, plastic scintillators and scintillating fibers, pure Csl scintillators.
