摘要： A low-velocity electron excited phosphor having a composition represented by a general formula ZnO.multidot.(Al.sub.x, Ga.sub.1-x).sub.2 O.sub.3 :Mn, wherein X=0.001 to 0.3 mol. A content of Al in the phosphor is set be to within a range between 0.001 mol and 0.3 mol. The range permits a variation in luminance of the phosphor to be within .+-.30% and initial luminance of the phosphor to be significantly increased, resulting in the phosphor being suitable for use for a fluorescent display device.

摘要： A process for producing a manganese activated zinc orthosilicate phosphor. An aqueous dispersion is prepared including fumed silica having an ultrafine average particle size of less than 50 nm, a zinc precursor, and a manganese precursor. The molar ratio of zinc:silicon in the dispersion is approximately 1.3:1 to 2.0:1, and the molar ratio of manganese in the dispersion is sufficient to activate the phosphor. The precipitate from the dispersion is calcined in an inert atmosphere at a temperature and for a time sufficient to form a manganese activated zinc silicate phosphor having a broad band emission peaking in the green region of the visible spectrum when stimulated by external radiation at approximately 254 nm. The calcined phosphor may be milled to achieve an average particle size of less than 5 .mu.m, the milling step being performed without significant loss of plaque brightness. Also disclosed is a green emitting manganese activated zinc silicate phosphor having an average particle size of less than 5 .mu.m and excellent brightness.

摘要： Encapsulated electroluminescent phosphor particles and method for making same. The phosphor particles are encapsulated in a very thin oxide layer to protect them from aging due to moisture intrusion. The particles are encapsulated via a vapor phase hydrolysis reaction of oxide precursor materials at a temperature of between about 25.degree. C. and about 170.degree. C., preferably between about 100.degree. C. and about 150.degree. C. The resultant encapsulated particles exhibit a surprising combination of high initial luminescent brightness and high resistance to humidity-accelerated brightness decay.
