In this work, we present a new photochromic tungstate based glass which have both absorption coefficient and refractive index modified under laser exposure. The photosensitive effect is superficial under ultraviolet (UV) irradiation but occurs in the entire volume of the glass under visible irradiation. The effect can be obtained in any specific point inside the volume using an infrared femtose...

During the dark adaptation of the human eye, its visual threshold decreases to a small fraction of its original value in the light. An analysis of the quantitative data describing this adaptation shows that it follows the course of a bimolecular chemical reaction. On the basis of these findings it is suggested that visual reception in dim light is conditioned by a reversible photochemical react...

This paper describes the present status of aging studies in various photosensitive detectors. New experimental data are presented on aging of trimethylamine (TMA) and ethylferrocene (EF) photosensitive vapors as well as on CsI and SbCs photocathodes. A new explanation of the aging process for CsI photocathodes based on solid –state physics theory is given. Finally, based on our studies, a gener...

This work investigates the synthesis of Cesium (Cs) based all-inorganic (CsPbBr 3 ) perovskite single crystals (PSCs) at low temperatures (45 °C) for application in photosensitive devices.
