High light yield liquid scintillator
WebSep 2, 2024 · Light yield ( LY) is an essential parameter for a scintillator as it directly influences the energy resolution at low or medium energy through the photostatistic term proportional to ( LY) −1/2 and the timing resolution proportional to ( τ sc / LY) −1/2, with τ sc being the scintillation decay time.
