Method of improving the maintenance of a fluorescent lamp containing europium-activated barium magnesium silicate phosphor |
摘要 |
The initial power output and maintenance of a fluorescent lamp containing europium-activated barium magnesium silicate phosphor is significantly improved by combining the phosphor with a flux and subjecting the phosphor/flux mixture to a refiring and rewashing process before applying the phosphor to the interior of a fluorescent lamp envelope. Surface concentrations of europium and barium are significantly increased, while surface concentrations of magnesium and silicon are decreased.
