PbS quantum dots (QDs) embedded glasses have been investigated for decades, but their
applications are limited to the color filters and saturable absorbers for laser pulse generation …

Saturable optical elements lie at the cornerstone of many modern optical systems. Regularly
patterned quasi-planar nanostructures—metasurfaces—are known to facilitate nonlinear …

PbS quantum dots (QDs) with a mean radii of 1.27 nm to 7.32 nm were precipitated in
alkaline-earth silicate glasses enriched in sulfur. A transmission electron microscope image …

A survey of results on use of semiconductor-doped glass saturable absorbers for near-
infrared passively mode-locked and Q-switched solid-state lasers is presented. Nanosized …

Lead chalcogenide quantum dots have particular optoelectronic properties induced by the
quantum confinement effects and have promising potentials towards applications in infrared …

We report measurements of the saturated intensities, saturable absorption, and nonlinear
refraction in 70-nm thick films containing 4 nm HgTe quantum dots. We demonstrate strong …

PbS quantum dots synthesis in boro-silicate glass is presented. Absorption bleaching of PbS
quantum dots of≈ 4 and≈ 7nm in diameter dispersed in this glass has been studied …

Tunable absorption and photoluminescence (PL) of lead chalcogenide quantum dots (QD s)
doped in glasses due to the quantum confinements effect have been actively investigated for …

A novel two-color photoluminescence (PL) is found in MnF 2 at room temperature under
high pressure. Contrary to low-temperature PL, PL at room temperature is unusual in …
