Abstract

PURPOSE:To provide light emitting glass consisting of Eu2O3, R2O3 (R is an element such as Sc), MO (M is an element such as Mg) and B2O3 in a specified component ratio and having characteristics such as high luminance, a low softening point and very low water solubility. CONSTITUTION:This light emitting glass having an emitted light distribution in the visible range when excited by ultraviolet rays has a composition represented by a general formula xEu2O3.yR2O3.zMO.vB2O3, wherein R is at least 1 kind of element selected from Sc, Y, La, Gd and Lu, M is at least 1 kind of element selected from Mg, Ca, Sr, Ba and Zn, 0.01<=x<=10mol%, 1<=y<=20%, 30<=z<=50%, 30<=v<=80% and 0.01<=x+y<=20%. Starting materials giving said composition by calcining are mixed and melted by heating in air at about 1,200 deg.C for >= about 2hr. The melt is quenched by charging into water, dried, pulverized, and used as said glass.

いる２は言−難かった。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a light-emitting glass that has a visible luminescence distribution when excited by ultraviolet light.Although light-emitting glasses have been known in the past, their luminous intensity cannot be said to be high and their use in various applications is limited. It was hard to say that 2 was fully functional.

50℃~750"O), syneresis solubility (water solubility #LO~2
%), and can be used in a wide range of applications. First, in the process of making a fluorescent lamp, this glass powder is coated on the glass tube together with the phosphor while being exposed to temperature in an aqueous solution, thereby improving the binding between the phosphor and the glass tube. This glass powder emits red light when excited by the mercury vapor resonance line, and is therefore useful for improving the color rendering properties of fluorescent lamps. Secondly, it is easy to process, so it is useful as a glass fiber for optical transmission fibers, signal transmission sensors, etc. Four kings are used for various purposes as decorative glass products, and can also be processed into ornamental ornaments, jump glasses, etc.
