We determine the extinction values of silver nanoparticles as a function of their diameter for
three different wavelengths (405 nm, 532 nm, and 671 nm) from the values of absorbance …

Binary liquid mixtures are studied using femtosecond pump− probe thermal-lens (TL)
spectroscopy. Changes in the measured TL signals as a function of relative concentration of …

This work reports on photothermal lens spectra of silver nanoparticles of different
dimensions in the spectral region of 370–730 nm performed using an arc-lamp-based …

We developed a pump-probe photothermal lens spectrophotometer that uses a broadband
arc-lamp and a set of interference filters to provide tunable, nearly monochromatic radiation …

Based on experimental results, we demonstrated that the most widely used model for the
description of the dual beam transient thermal lens spectroscopy technique also works well …

We describe a two-beam thermal lens spectrophotometer that uses a xenon lamp as the
excitation source and a low power diode pumped Nd-YAG laser as the probe light. The …

We present a mode-mismatched continuous wave (cw) achromatic thermal lens experiment
in which the pump beam is focused in the presence of a collimated probe beam. This …

Abstract Effect of isotope substitution from the modulation of Thermal-Lens (TL) signals in
binary liquid mixtures is explored using femtosecond pump–probe mode-mismatched Z …

We present a spectroscopic method for measuring the fluorescence quantum efficiency
$({{\rm {\Phi}}} _ {f}) $ of fluorophores that does not require calibration standards …

It has been shown that a top-hat excitation beam gives rise to a more sensitive signal for the
thermal lens spectroscopy (TLS). Recently, a numerical model has been presented for a top …
