Method to Analyze Physical and Chemical Properties on the Surface Layer of a Solid
First Claim
1. A method for analyzing physical and/or chemical properties of the solid body comprising the activation of said solid body by activating irradiation coming from outside of analyzed solid body, the deactivating of the solid body, and the recording of the spectrum of the energy quanta emitted by the solid body, wherein:
- a. the activating irradiation is used as single pulse and its dose and exposure is chosen in such way that said activating irradiation penetrates not through the whole volume of material but only through the limited surface layer of said solid body without sufficient damage of said surface layer by activating irradiationb. termination of said activating irradiation;
c. after termination of said activating irradiation said solid body is deactivated by keeping the solid body at a constant temperature (isothermal luminescence) and subsequently heating it when the isothermal luminescence is over;
d. the spectrum of the energy quanta emitted by the surface layer of the solid body, activated by aid activating irradiation, is recorded during the deactivation in such a way that the spectrum of the emitted energy quanta recorded at a constant temperature provides (isothermal Luminescence) data on the loosely coupled states of the surface layer and their half-lives, while the followed thermo-luminescence spectrum recorded during the heating gives information on the phase and relaxation transitions in the surface layer.
