Method of forming a high efficiency phosphor for photochromic glass information display systems |
| abstract |
A process for making BaSi2O5:Pb having a high energy conversion efficiency of ultraviolet emission under electron bombardment. The process includes mixing BaCO3, BaF2, Pb(NO3)2 and SiO2 in a form having extremely small particle size so as to facilitate complete dispersal of the SiO2 in the mixture. Pb(NO3)2, a soluble salt, is mixed with the other ingredients in a slurry of alcohol. The soluble salt dissolves in the alcohol to obtain complete dispersal of lead throughout the mixture. After mixing the other ingredients and before firing, H3BO3 is added. The product BaSi2O5:Pb is used as a high efficiency phosphor in combination with photochromic glass in an information display system. |
