“…1). As a measure of the laser dye quality [17] the quantum efficiencies q of dyes 1 and 2 were determined from plots of dye laser energy outputs (EDye) vs. pump laser energy (E~xc) as presented in . Dye laser output with PCI dyes 1 (at 564 nm) and 2 (562 nm) and with rhodamine 6G (565 nm, in methanol) vs. pump laser energy tuning ranges were: 7/=0.29 at 564nm for dye 1, q = 0.21 at 562 nm for dye 2 and q = 0.40 at 565 nm for Rh 6G.…”

Abstract. The laser performance and related photophysical properties of two very soluble perylene dyes with long chain secondary alkyl groups were investigated in cyclohexane solution. With a dye laser as pump source a tuning range of 555-580 nm was obtained at an optimum concentration of 3 x 10 -4 M. The quantum efficiencies (7 =0.29 and 0.21) were better than 1/2 that of rhodamine 6G. No photodegradation was observed over an excitation period of several hours.

The singlet absorption, triplet absorption and the absolute fluorescence spectra together with the fluorescence quantum yields and fluorescence decay times as well as the laser performance (tuning range, conversion efficiency, photochemical stability) of nine fluorescent brightening agents have been measured in ethanol at room temperature. High fluorescence quantum yields of over 0.75 with short fluorescence decay times of well under one nanosecond have been obtained. With the exception of two fluorescent brightening agents the tuning ranges are in the violet‐blue region between 415 and 447 nm. The conversion efficiencies range from 1 to 15%. The photochemical stability of the optical brighteners in solution with energy half‐life values between 2 × 104 and 105 J/l, corresponding to average lifetimes of 75 to 200 photons per molecule, is poor in comparison to their known photochemical stability in the adsorbed state.
