Fabrication of columnar CsI and CsI:Na scintillation films deposited by vacuum thermal evaporation at high deposition rates

Controlling Void Contents in the Zn Interlayer for Improving Adhesion Strength of ZnMg/Zn Bilayer Coatings on TRIP Steel

“…This phenomenon could be attributed to the fact that Zn atoms partially lose their kinetic energy by colliding with other Zn atoms in vapor gas while they traverse the vacuum chamber from the source to the substrate. 22,23) As a result, the formation of void structures at high input current, i.e., high partial pressure (see Table 2), could be attributed to the reduction in the Zn adatom surface mobility relative to the low input current.…”

Research progress on preparation methods and deliquescence resistance of micro-columnar CsI scintillation films

“…In 2015, Ma et al deposited a 250-nm-thick Parylene-N film and a 1-μm-thick Al film on the surface of CsI films respectively 35 . Then both of them were exposed to air for more than 40 days.…”

Photoluminescence of Cesium-Doped Sodium Iodide Films Irradiated by UV LED

“…These inorganic compounds can be classified into intrinsic, involving direct electron-hole recombination, and extrinsic, associated with impurities and additive dopants [23]. Among these materials, alkali metal halides are the most widely used compounds because of their efficient scintillation [24,25]. Examples include sodium iodide (NaI), cesium iodide (CsI), cesium fluoride (CsF), potassium iodide (KI), and lithium iodide (LiI).…”

“…Na-doped CsI, one of the brightest available scintillators, has emission wavelengths between 280 and 350 nm [6]. CsI:Na crystals have been studied in detail with a variety of fabrication methods, such as direct seeding [44], thermal vacuum deposition [25], and the edge-defined film-fed growth (EFG) method [45].…”
