According to the Lambert-Beer law A = [epsilon]bc, and the apparent molar absorption coefficient, [epsilon] = 4.71 x [10.sup.5] L x [mol.sup.-1] x [cm.sup.-1] was calculated.
As was shown (Figure 4), aggregation of the above dyes leads to the band broadening and decreasing molar absorption coefficient rather than appearance of a new band.
where [integral] [epsilon]([upsilon])d[upsilon] [approximately equal to] [epsilon]([upsilon]) x [DELTA][upsilon] and [epsilon]([upsilon]) is the molar absorption coefficient at frequency n([cm.sup.-1]) and [DELTA][upsilon] is the band width at 1/2 [epsilon]([upsilon]) measured directly from absorption spectra (FWHM) "Origin-8.5" software.
In this region of the spectrum, the molar absorption coefficient of the nanoparticles, [[epsilon].sub.CdSe], is independent of their size.
The basis for determining the concentration of followed species is Lambert-Beer law which establishes the connection between the optical absorbance A of the colored solution, thickness of the photometrical layer b, molar absorption coefficient a and the concentration c of the species observed:
At 365 nm, the most widely utilized irradiation wavelength for photocuring, BCTE-HABI has a molar absorption coefficient [epsilon] = 2300 [mol.sup.-1] 1 [cm.sup.-1], which is much higher than that of o-Cl-HABI [epsilon] = 572 [mol.sup.-1] 1 [cm.sup.-1].
