Abstract
In this paper, we present our study on the spectral discrimination between high and low quality tobacco leaves using a time-resolved ultraweak luminescence detection system. Photoinduced delayed luminescence (DL) is employed as a nondestructive and objective indicator of tobacco leaf quality. DL decay kinetics of tobacco leaf samples is measured, and the data are fitted by a hyperbolic cosecant function. Results show that the function’s parameter A is significantly related to the quality grades of tobacco leaves—compared with the low quality tobacco leaves, an increase of the A value by a factor of 7 is obtained for the high quality tobacco leaves. Research from this work contributes to the development of a novel optical method applicable for the quality evaluation of agricultural crops and food products.
