The primary 150[degrees]C glow peaks disappeared upon preheating at temperatures from 250[degrees]C to 341 [degrees]C (near the melting temperature of PEEK), but then new thermoluminescence is detected at near 75[degrees]C of the TSL glow curve.
Key Words: Thermoluminescence, Glow curve, Chain scission.
A glow curve
reader was assembled using a fabricated microcontroller-based temperature programmer, SES regulated power supply (1050 volt.
In the glow curve, the thermally stimulated luminescence (TL) monitors photons as a function of temperature during a thermal scan.
The duration time of 1000 h or 2000 h has no further influence on the shape of the glow curve.
The glow curve patterns of natural, gamma exposed (raw and annealed) samples are discussed.
The TSL glow curves were recorded immediately after irradiation to avoid loss due to fading.
Paleodose and the supralinearity correction factor were determined by analyzing the glow curve
in the temperature range of 250 to 400[degrees]C and giving additive laboratory doses.
On heating of the sample, TL is manifested in the form of a glow curve
In the present investigation, an attempt was made to study the TSL glow curve
characteristics of six calcite samples which were collected from Padaivedu mines of Namakal district, Tamilnadu.
The glow curves
of thermoluminophors were measured by a thermoluminescence reader (TLD reader) UPF-02 (Moscow, Russia).
Following X-irradiation and subsequent heating in the temperature interval 23-200[degrees]C, TL glow curves
produced characteristic emissions near 75[degrees]C and 100[degrees]C from the crystalline and amorphous regions, respectively.
