摘要： Luminescent crystals of the activated rare-earth oxybromide type are coated with a layer of a double salt metal lanthanum sulfate, such as aluminum-lanthanum sulfate or an alkali-lanthanum sulfate, so as to stabilize the resultant luminescent material against humidity without adversely effecting the luminescence capability of such material. The humidity-stabilized luminescent materials of the invention are useful in luminescent coatings or the like employed in medical x-ray diagnoses for intensification of radiation effects on radiographic exposure films. Such intensification coatings generally are incorporated within x-ray intensifier foils.

摘要： In a method of preparing a luminescent aluminate comprising aluminium and one or more of the metals yttrium and elements of the lanthanum series the component metals of the aluminate are co-precipitated from aqueous solutions of salts of these metals by combining these salts with a precipitation agent comprising carbon dioxide and ammonia in a quantity from 1 to 3 mole per mole of carbon dioxide. Such a quantity of the precipitation agent is used that the molar ratio of the carbon in the precipitation agent to the sum of the metals in the salts has a value from 1 to 10, a higher value in that range being chosen for this ratio according as the desired average grain size of the precipitate is larger. Finally, the precipitate obtained is heated at an elevated temperature.
