Abstract
Luminescence from γ-irradiated high density polyethylene doped with naphthalene and pyrene was investigated. Excimer emission of the aromatic admixture was observed in the temperature range (200–230 K) of the high temperature radiothermoluminescence peak. During nanosecond pulse radiolysis, traces of excimer emission were recorded in the same temperature range. Pyrene excimer emission was observed from pulse-irradiated samples at room temperature. The mechanism of excimer formation is discussed.
