TABLE 1.
Overlap between the absorption spectra of the PSs and the emission spectrum of the diode array
| PS | Absorption peak (half peak width) (nm) | Extinction coefficienta | % Overlap with light emission | Light doseb |
|---|---|---|---|---|
| ce6c | 658 (22) | 30,000 | 35 | 79.5 |
| CMA | 658 (24) | 28,000 | 37 | 78 |
| Conjugate | 662 (28) | 20,000 | 66 | 100 |
| BPD | 687 (19) | 50,000 | 24 | 91 |
a
Measured in 0.1 M NaOH–1% sodium dodecyl sulfate.
b
The relative effective light dose absorbed by each PS is defined as extinction coefficient × overlap with diode emission in percent and was expressed as percentage of that absorbed by the conjugates.
c
No difference in the spectrum was observed when ce6 was mixed with pL.
