Spectral Hole-Burning Study of Neutron-Irradiated Diamond
A spectroscopic investigation of a neutron-irradiated IaB-type natural diamond crystal was carried out. Persistent spectral hole-burning in the absorption lines of n-irradiation induced defect aggregates at 649.5, 655 and 681 nm was performed at 5÷200 K. By virtue of the high Debye temperature of the diamond the holes burnt in 655 nm line were observable up to ∿200 K. A weak temperature dependence of the holewidth indicates to the interaction with the localized structural instabilities, created by heavy doze irradiation.
