Radioluminescence of methylcyclohexane in the glassy state
The radioluminescence of pure, frozen methylcyclohexane (MCH) has been investigated. λ-Irradiation of MCH at 77 K produces at least three negative species—trapped electrons, e-t, and two types of anions, which are formed in the reactions of electrons with radicals, R-, and with stable radiolysis products, P-. It is shown that the radiothermoluminescence (RTL) emission is due to the recombination of et-(RTL peak at 90 K) and R-, P- (RTL peak at 95 K) with cations. The intensity-dose dependence of the RTL peaks has been interpreted using a simple kinetic model.
