Structure Characterization and Luminescence Studies of MgO:Li Calcinated at Different Temperatures via Solution Combustion and Sol-Gel Methods
Abstract
In the
present study, lithium (Li) doped magnesium oxide (MgO) samples were prepared
using Solution Combustion Synthesis (SCS) and Sol-Gel (SG) methods. Their
photoluminescence (PL) and thermoluminescence (TL) behaviors were determined
after the different calcination temperatures. The aim of this study is to
investigate the effect of different calcination temperatures on the PL and TL
sensitivities of lithium doped MgO (MgO:Li) samples in pellet and powder forms
prepared by SCS and SG methods. The structural characterization analysis of
MgO:Li powder and pellets were carried out using X-ray diffraction (XRD) and scanning
electron microscope (SEM) methods. The results of these structure analysis
showed that MgO:Li samples have different crystal properties when changing
calcination temperatures were applied during the preparation of the samples.
Luminescence properties of the MgO samples which were synthesized at different
calcination temperatures were investigated by the Photoluminescence (PL) and TL
techniques. The maximum TL intensity of the samples was obtained at calcination
temperature of 800 and 1000 oC for the SCS and SG methods, respectively.
Uncontrolled chromium impurities were observed in MgO samples by using PL
measurements. On the PL spectrum, peaks indicating chromium (III) (Cr3+)
transmission in the red portion of the spectrum at 672, 698 and 721 nm are clearly
evident. We investigated high dose sensitivity in these samples. This study
presents optimum calcination temperatures in order to obtain maximum PL and TL
sensitivity of MgO sample. It is also clear that it will contribute to the
literature that it can be studied as a new dosimetric material.
