Radiothermoluminescence of surface layers of n-tetracosane crystals
- 30 Downloads
A radiothermoluminescence (RTL) curve of surface layers of n-tetracosane crystals has been obtained, which appear to be similar but not identical to the RTL of the evacuated sample or the sample with CCl4. Since CCl4 does not penetrate the crystal, the difference between the RTL curves of the evacuated sample and the one with CCl4 represents the RTL of crystal surface layers. The RTL curve of tetracosane with the scavenger is that of RTL of intracrystalline areas of the alkane. The difference in shape between the surface and bulk RTL curves is manifested well in the ratio of the RTL curves for the surface and the evacuated sample.
