Abstract

Polyethylene terephthalate (PET) and polyethylene naphthalate (PEN) are both good candidates for use as scintillation base substrates. One advantage is their relatively high density of 1.33 g cm-3. To enhance their relative strengths and to mitigate their weaknesses, we blended PET and PEN 1:1 by weight and found that the overall characteristics are improved. The wavelength at maximum emission was 415 nm, the refractive index was 1.61, and the light yield was 0.85 times that of PEN. These results increase the available options for base materials to be used as scintillators.
