Abstract

A portable CCD spectrometer was applied for the measurement of photoluminescence (PL) spectra of alkali feldspars. A calibration was carried out for the spectral sensibility of the system. PL spectra with different patterns were measured for the red and white PL of zoned alkali feldspars from the Tanakami granite pegmatites, Shiga Pref. The PL spectra of alkali feldspars principally consist of an intense emission band in red region and a weak emission band in blue-green region.
