Fig. 1 Excitation/emission
spectra of 3H2NAwith
concentration of 2.0×10−5 M
(lower intensity), and in the
presence of Al3+ ions (5.0×
10−6 M) with a considerable
enhancement intensity and shift to
other wavelengths (higher
intensity). The spectra were
recorded from the buffered
solutions (pH 4.5) by keeping the
excitation/emission wavelengths
at 366 and 465 nm, respectively
