    摘要： In a method of preparing a phosphor or scintillator layer to become deposited on a support, a vapor depositing step is applied from a crucible unit by heating as phosphor precursor raw materials present in said crucible, a Cs(X,X′) matrix compound and an activator or dopant precursor compound, wherein said crucible unit comprises at least a bottom and surrounding side walls as a container for phosphor precursor raw materials present in said crucible in liquefied form after heating said crucible, and wherein said Cs(X,X′) matrix compound has a higher vapor pressure than said activator or dopant precursor compound, said method comprising a step of providing said activator or dopant compound in form of a precursor raw material represented by the formula CsxEuyX′(x+αy), wherein x, y and α are integers, wherein x/y is more than 0.25 and wherein α is at least 2, wherein X represents Br and wherein X′ stands for F, Cl, Br, I or a combination thereof; followed by an annealing step after a vapor depositing step, provided that said annealing step proceeds in an ambient atmosphere after cooling said phosphor or scintillator layer, deposited on said support; and wherein as a result a binderless needle-shaped Cs(X,X′):Eu phosphor or scintillator layer becomes provided, having on top of its needle-shaped phosphors, aligned in parallel, an average ratio of divalent to trivalent europium dopant of more than 1:1; wherein said average ratio decreases to an extent of less than 2% per hour, while being exposed to X-rays having an energy in the range from 1 to 100 keV.

    摘要： A method of making a lithographic printing plate including the steps of a) image-wise exposing a lithographic printing plate precursor including a light or heat sensitive coating on a support having a hydrophilic surface or which is provided with a hydrophilic layer, and b) processing the precursor consecutively with a first solution and a second solution thereby removing the coating from the support in the non-printing areas. The first and second solutions are provided by a cascade system such that the second solution overflows into the first solution and the first solution overflows into a container to be further treated as waste, and the second solution is regenerated by adding a replenishing solution or a mixture of replenishing solutions at a rate of at least 5 ml/m2 of treated precursor and at most 30 ml/m2 of treated precursor.
