in this scientific research zns nanoparticle was synthesized via precipitation method. two samples were synthesized by this method. the nanoparticle was characterized by xrd techniques, and the size and kind of crystallinity were identified by x-ray diffraction pattern as well. the size measurement has been done by using scherrer's equation. the average sizes of nanoparticles in two sample...

Thermoluminescence (TL) studies of insulators, including crystals of minerals such as calcite, quartz or zircon, have resulted in the development of a wider range of applications in the fields of radiation dosimetry and archaeological and geological dating. Most conventional TL measurements are made by recording light emission during heating by means of broad-band optical filters and blue-sensi...

Luminescence occurs in almost all the materials absorbing photon energy and is a phenomenon of light emitting process. There are various types of luminescence, e.g. fluorescence, phosphorescence, delayed luminescence, chemiluminescence and thermoluminescence. In these cases, light is emitted when a photoor chomo-excited molecules is deexcited to its ground state. During this deexcitation proces...

In this paper, we present the first measurements on thermoluminescence from isolated thylakoids to probe the recombination reactions of S 2 (or possibly $3) with Q ~ or QA, after bicarbonate depletion and its readdition. The effects of bicarbonate depletion on the S2Q ~ (or 8 3 0 ~ ) thermoluminescence band was (1) a 6 1 0 ° C shift to a higher temperature; (2) a reduction in its intensity upon...
