UV-vis optical absorption spectra of CdS NCs ablated at various laser fluences for Sample A: , Sample B: , and Sample C: .
TEM images of the as-prepared CdS NCs and corresponding size distribution produced at different laser fluences: (left), (middle), and (right).
(a) Normalized room temperature PL emissions of CdS nanoparticles (excitation at 300 nm). The inset presents the normalized absorption and PL spectra of Sample B. (b) Size distributions (triangles) and photoluminescence spectra (squares) at FWHM as a function of the laser fluence.
Room temperature fluorescent decay curves of Sample B monitored at 370, 390, 420, 430, and 450 nm.
