Abstract:
This work covers Second order kinetics Thermoluminescence(TL) behavior of Titanium
oxide (TiO2). Theoretically show that TL intensity verses temperature With important
TL kinetic parameters . To investigate the Second order kinetics thermoluminescence
behavior Titanium oxide (TiO2)properties by using one trap and one recombination
model (OTOR). According to prefer Titanium oxide (TiO2) in second order equation
(Garlick Gibson). We have get different characteristics of glow peak curves, the values
of kinetics parameters are changed then as follows.
• Firstly the activation energy changes the glow curve can be goes from minimum
to the maximum of temperature, because of when we used the large activation
energy to use more charges moves from valance band to conduction band,if lower
activation it has large glow curves but the larger activation the small glow peak
curves.
• Secondly the TL intensity peak shifts slightly to higher temperature a glow curve
peak maximum with change (increase) heating rate. These glow curves shift.
• Thidly a glow curve peak maximum with change in concentration of electron the
glow curves verses to the concentration of electron increases,and the height of
the thermoluminescence peak changes to the high temperature and intensity of
thermoluminescence also increases these glow curves unique from experimental
glow curves .
• Finally a glow curve peak maximum with increases in frequency factor and,increases
the frequency to need small amount of energy needed trigger the charge therefore
glow curve shift to from maximum to lower temperature ,and intensity ofbthermoluminescence also decreases. Therefore studying luminescence properties for
possible applications such as long lasting phosphorescence and display devices.
