Abstract Title: The Thermographic Phospor Labkit
Abstract: The thermographic phosphor (TGP) lab kit is a flexible instrument for students beyond the first year and is also a useful laboratory tool for physics research and development.  As to be described, it aids in teaching and demonstrating a number useful concepts and skills.  Students will learn important aspects of optical physics and spectroscopy.  By producing fluorescence and measuring its characteristics versus temperature,  students will become familiar with  atomic energy levels, lifetimes, radiative and non-radiative transitions, spectral bands and linewidth, spectral distribution, and absorption.  In addition, measurements involve optics, electro-optics, and electronic instrumentation.   Practice and familiarity with common laboratory and industry tools such as thermocouples, Peltier devices, and photomultiplier detectors also contribute to the educational objectives.  Finally, in the course of exercising the instrument, the student will learn the practical skill of temperature measurement and control.   The labkit contains an ultraviolet light emitting diode of 365 nm that illuminates a thin phosphor layer.  The phosphor adheres to a copper plate in intimate contact with a Peltier heater/cooler that covers 0 to 100 °C.  A thermocouple attaches to the copper plate to monitor temperature.  The lab kit allows for controlling the pulse duration of the LED and the rate of repetition.
