suitability suitable for scintillation
Application: PPO can be used as a dopant that improves the photo-electric feedback of plastic scintillators which are used as radiation detectors for nuclear materials. It can be coated on peptide substrates to facilitate radioactive labelling which can enable determination of substrate specificity of lysine methyltransferase enzymes. It may also be used in the fabrication of organic luminescent materials which can be used in light emitting diodes (LEDs).
General description: 2,5-Diphenyloxazole (PPO) is an oxazole that can be used as a scintillator and a laser dye. It has fluorescence at a wavelength of 375 nm. It can be used as a wavelength shifter in liquid samples due to their high quantum yield and large strokes shift.
