It is also used as a green phosphor in projection CRTs, though its drawback is marked lowering of efficiency at higher temperatures. Variants include, for example, using praseodymium instead of terbium ( CAS registry number 68609-42-7 , EINECS number 271-826-9), or using a mixture of dysprosium and terbium for doping (CAS number 68609-40-5 ...

Here is a list of radioisotopes formed by the action of cosmic rays; the list also contains the production mode of the isotope. [4] Most cosmogenic nuclides are formed in the atmosphere, but some are formed in situ in soil and rock exposed to cosmic rays, notably calcium-41 in the table below.
Phosphoric acid (orthophosphoric acid, monophosphoric acid or phosphoric(V) acid) is a colorless, odorless phosphorus-containing solid, and inorganic compound with the chemical formula H 3 P O 4.
An active search is underway for a 66-year-old Michigan woman who disappeared from a popular tourist hot spot during a trip to the Grand Canyon more than a week ago, officials said.
Polycrystalline Mn:SrAl 12 O 19 is used as a green phosphor for plasma displays, and when doped with praseodymium or neodymium it can act as a good active laser medium. Sr 0.95 Ce 0.05 Mg 0.05 Al 11.95 O 19 is a phosphor emitting at 305 nm, with quantum efficiency of 70%. Several strontium aluminates can be prepared by the sol-gel process. [6]
