Thermo-luminescence

Thermo luminescence is the emission of light by moderately heated electrically insulating solids. Many minerals, rocks, and ceramics, when heated to a high temperature but below that required for them to become incandescent, emit light. The emission of light is related to the structure and previous environmental conditions of the solids. All solids on the earth s... [Pg.121]

That x-rays render various substances strongly thermo-luminescent has already been shown.1 The following experiments have been made to determine the subsequent effect of ozone upon such materials. [Pg.6]

H. Konen showed that the thermo-luminescence of iodine vapour begins at about 550°, and is stronger the denser the vapour, and he adds that the glow spectrum of iodine is specially interesting because it is one of the few cases where a visible spectrum is obtained by merely heating a gas. According to W. Friederichs, the banded... [Pg.61]

The heat of desorption can be deduced more simply from the maximum in the rate of evolution. The maximum rate as well as the surface concentration at the maximum, both of which enter into Eq. (12), can be obtained directly from the curve of evolution rate vs time or temperature. The graphical integration required for n can be avoided in simple first-order reactions by adopting a procedure customary in the study of thermo-luminescence. On substituting for d In nidi from Eq. (9), Eq. (12) rearranges to... [Pg.281]

The toxic effect of nickel (Ni) on photosynthetic electron transport was investigated by monitoring the Hill activity, fluorescence, oxygen evolution and thermo-luminescence properties in the green algae Scenedesmus obliquus. The results obtained surest that Ni modify the Qp site or interact with the nonheme iron between the Qa and Qp inhibiting the photosystem II functions. ... [Pg.168]

More recently, however, we happened to observe that even in the treated membranes the EPR multiline signal can be induced, if illumination is given at higher temperatures. This finding led us to investigate the temperature dependence of to S2 transition. In this communication we report a precise comparison of the temperature dependence of to S2 transition by means of thermoluminescence and low temperature EPR spectroscopy between low pH treated and normal untreated PSII. It was found that low pH treatment not only modulates the properties of the S2 state as represented by elevated peak temperature of thermo luminescence and narrowed hyperfine line spacing of the multiline signal, but also markedly upshifts the threshold temperature of to S2 transition. [Pg.702]
