A technique using temperature pulses was used to measure thermoluminescence in single aluminum oxide microparticles. This method can excite a large fraction of trapped carriers to luminesce simultaneously, which increases the maximum intensity and makes it ideal for probing the luminescence of micro- and nano-particles. Using 50 ms and 10 ms pulses, the technique resulted in curves similar to standard thermo luminescence curves with peaks near 240degC and 300degC respectfully. Increasing the… Expand
