Study of influence of pre-heat treatment on thermoluminescence glow curve pattern and related trapping parameters of technologically important synthetic quartz specimen

107-110<span style="font-size: 15.0pt;mso-bidi-font-size:8.0pt;font-family:" times="" new="" roman","serif""="">The observed thermoluminescence(TL) glow curve patterns of laboratory grown synthetic quartz have been plotted as glow peak intensity ratio of low temperature glow peak to that of high temperature glow peak against either duration or temperature of pre-heat treatment. Systematic changes in this intensity ratio with the changes in pre-heat treatment conditions are observed. The systematic shifting of TL glow peak position towards lower temperature side with the changes in duration of pre-heat treatment has also been reported. The observed facts are explained on the premise of colour centres <span style="font-size: 15.0pt;mso-bidi-font-size:8.0pt;font-family:" times="" new="" roman","serif""="">involved and phase transformation of quartz specimens when pre-heat treated at high temperature. The interpretations are well-supported by trapping level characterization also.
