Totally visible transparent chloro - Sulphide glasses based on Ga 2S3 - GeS2 - CsCl
(2007-01-01)
In this paper, the influence on optical properties of alkali halides such as CsCl in a covalent glassy matrix has been investigated. Chalcogenide glasses belonging to the (GeS2)-(Ga2S3)-CsCl system with high ratio of CsCl ...
IR-visible upconversion and thermal effects in Pr3+/Yb3+-codoped Ga2O3 : La2S3 chalcogenide glasses
(Iop Publishing Ltd, 2000-12-04)
IR-visible upconversion fluorescence spectroscopy and thermal effects in pr(3+)/Yb3+-codoped Ga2O3:La2S3 chalcogenide glasses excited at 1.064 mum is reported. Intense visible upconversion emission in the wavelength region ...
Evacuation under limited visibility
(World Scientific, 2015-01)
A multiplicity of situations can trigger off an evacuation of a room under panic conditions. For "normal" (with "normal" meaning absence of obstacles, perfect visibility, etc.) environmental conditions, the "faster is ...
Constructing Heterocycles by Visible Light Photocatalysis
(Bentham Science Publishers, 2017-05)
Heterocycles are widely spread in natural products and in many bioactive compounds, as well as in a variety of fine chemicals. Synthesis through catalysis is always an advantageous strategy and today it is difficult to ...
