BC-414 Premium Plastic Scintillator General Description This new PVT-based plastic scintillator is formulated for use with wavelength shifter (WLS) bars having short decay times. The traditional green WLS (wavelength shifting) plastics, intended for use with many common blue emitting scintillators, have long decay times - typically 15 nsec. To meet the need for scintillator-WLS systems with faster time response, Bicron developed BC-414 and also the WLS plastic BC-484. While having a relatively short emission spectrum for optical compatibility with BC-484, BC-414 still possesses sufficient transparency to its scintillation light for it to be used in plate sizes of at least 50 cm (20 inches) on a side. Shorter wavelength scintillators, with emission peaks typically at 375 nm, have extremely short light attenuation lengths (<10 cm) which limit their useful sizes.
