A Low-Cost Time-Resolved Spectrometer for the Study of Ruby Emission
McBane, George C.; Cannella, Christian; Schaertel, Stephanie
Journal of Chemical Education, v95 n1 p173-177 Jan 2018
A low-cost time-resolved emission spectrometer optimized for ruby emission is presented. The use of a Class II diode laser module as the excitation source reduces costs and hazards. The design presented here can facilitate the inclusion of time-resolved emission spectroscopy with laser excitation sources in the undergraduate laboratory curriculum. The ruby decay data show evidence of radiation trapping, an interesting optical phenomenon discussed in the research literature.
