Figure 3
Effect of NaOH treatment on the decay time distribution. Rapid (τ1) and slow (τ2) decay time distributions evaluated from FLIM image and the corresponding average decay time (τ) for bagasse treated with H2SO4 1%, NaOH 0.5%, 2% and 4%. The same distributions are also presented for the eucalyptus fiber and the lignin film for comparison. The factor 0.2 was used just to set the counts to a convenient value just to get a better comparison among distributions.
