The fluorescence quantum efficiency of crystal is up to 37% and an emission peak maximum (λmax) locates at 645 nm.
In moving from mono- to di-substituted triazine derivatives the absorption maximum (λmax) shows a negligible shift, but the β values are enhanced.
Changes in the optical properties of the nanoparticles due to DNA-probe binding are reflected in the shift of LSPR extinction maximum (λmax).
The measured wavelength of the optical absorption spectrum peak maximum λmax showed a continuous increase with increasing chain length up to lengths of nearly 5000 repeat units.
Table 2 lists the maximum λmax, valley λmax, and the corresponding reaction time needed to reach them for the three reaction systems.
Table 2 The maximum λmax, valley λmax, maximum peak height of 780 cm- 1 band and the corresponding reaction time needed them to reach for the three reaction systems.
Its absorption maximum, λmax, at 520 nm in the visible range is quite sharp (2.8 × 104 M−1 cm−1 at 30°C).
Polymer PDPP1 displays an absorption maximum (λmax) at 892 nm with a shoulder at 796 nm in the solution, whereas the λmax of PDPP2 locates at 567 nm.
WT KR2 had an absorption maximum (λmax) at λ=524 nm and the N112A, Q123A, and Q123V mutant showed similar λmax values.
