Jl. Zhang et al., PHOTOSTABILITY, LASER ENERGY-CONVERSION EFFICIENCY AND ABSORPTION OF IR HEPTAMETHINE CYANINE DYES ABSORBING BEYOND 1 MU-M, Dyes and pigments, 28(1), 1995, pp. 1-6
The optical absorption, photostability and energy conversion efficienc
y of a series of heptamethine IR dyes are reported and results related
to chemical structure. The high photostability and high laser energy
conversion efficiency of several of the dyes indicate potential use in
IR dye lasers.
