Hypervelocity impact induced mechanoluminescence of phosphors [PDF]
, 2012 Phosphors are materials doped with one or more impurities that give cold light emission when excited. When a high velocity projectile strikes the backside of a metal plate whose front side is coated with phosphor, then the light emission takes place from

Critical mineral removal from mining‐impacted waters using microalgal biomass
The Canadian Journal of Chemical Engineering, EarlyView.Abstract Rising demand for critical minerals has led to increased mining and mineral processing activities, resulting in the release of metal‐contaminated waters requiring treatment. Conventional treatment methods, such as lime neutralization, effectively precipitate metals; however, they are less effective at low metal concentrations and produce large

Green Phosphors Based on 9,10-bis((4-((3,7-dimethyloctyl)oxy) phenyl) ethynyl) Anthracene for LED
Micromachines, 2019 An anthracene aromatic unit was introduced into the phenylethynyl structure by a rigid acetylene linkage at the C-9 and C-10 positions via Sonogashira coupling reactions, resulting in a planar and straight-backbone molecule (9,10-bis((4-((3,7 ...

Luminescent mechanisms of ZnS:Cu:Cl and ZnS:Cu:Al phosphors
, 2011 [[abstract]]ZnS:Cu:Cl and ZnS:Cu:Al phosphors are fabricated by a flux fusion method to be used in cathode ray tube (CRT) monitors for green emission. The emission spectra of the phosphors depend on the Cu concentration.

Photostimulated luminescence of BaFBr:Eu2+ phosphors
, 1996 After x-irradiation for 10 s, luminescence from BaFBr:Eu2+ phosphors by photostimulation of longer wavelength than F absorption bands was observed and assigned to the surface states or intrinsic defects of the powders.
