Non-Toxic Sulfide Glasses and Thin Films for Optical Applications

Preparation and properties of La2O3–Ga2S3 glass-ceramics for IR materials

“…In our previous study, isothermally-treated La 2 O 3 -Ga 2 S 3 glasses with a composition of 30 mol% La 2 O 3 -70 mol% Ga 2 S 3 homogeneously precipitated small needle-like crystals with 1-2 lm in length and with large numbers [7]. In this study, heat-treatment conditions, phase, microstructure, Vickers hardness and IR transmittance are studied for La 2 O 3 -Ga 2 S 3 glass-ceramics.…”

Exposure enhanced photoluminescence of CdS0.9Se0.1quantum dots embedded in spin-coated Ge25S75thin films

“…[37][38][39] In this work, we report on (a) "one pot" preparation and characterization of highly PL CdS 0.9 Se 0.1 nanoparticles (b) and their usage for doping of Ge 25 S 75 ChG solution. The Ge 25 S 75 ChG is non-toxic 40 and the thin lms were successfully deposited by spin-coating technique only recently. 31 The doped Ge 25 S 75 thin lms deposited by spin-coating technique were of good optical quality, well transparent in VIS and NIR and maintained PL of the QDs.…”

A study of silver halide fibers using fiber evanescent wave spectroscopy to assess the potential for in-vivo diagnosis of malignant cervical tissue

“…Among the chalcogenide glasses, AS2S3 is the most studied and best known. Chalcogenide glasses tend to have high refractive index as shown in table 4 [15]. Their absorption spectra also typically…”

“…show several sharp peaks as extrinsic contamination of hydrogen, water and OH" bonding is often present [15,16]. They are very stable and can be molded into optical glass components such as lenses [17].…”

“…Takebe and colleagues [15] studied the transmission spectra in the visible and infrared of a series of these glasses. In the visible range, the absorption edge is located in the 400 to 500 nm range.…”
