title: A simplified system for reading time-resolved photoluminescence.
abstract: A simplified system for measuring time-resolved photoluminescence (PL) induced by UV laser pulses (lambda = 337 nm) is designed by a combination of a commercial PL reader and a digital oscilloscope. Using this system, PL emissions after pulsed UV excitation from a chip of sapphire (Al2O3) are successfully measured with intervals of 10 ns. It is thus expected that this system will be conveniently used for searching new PL materials that would be more suitable for space radiation dosimetry.
