Structural tailoring of p-terphenyl scaffold: Towards advanced plastic scintillator

On the Origin of the Light Yield Enhancement in Polymeric Composite Scintillators Loaded with Dense Nanoparticles

“…The classical strategy to improve ϕ LY for polymeric scintillators is to use a second scintillating dye as an energy collector and transporter 53 to better harvest the deposited energy from the matrix while avoiding self-absorption effects. We opted here for TP, whose absorption spectrum is resonant with the PS D * emission at 320 nm (Figure 1a), resulting in a PS → TP Forster radius as large as R Fs PS→TP = 16.2 nm (SI, Section 5).…”
