ABSTRACT:
An improved fluorescent lamp and a method of preparing the same are described. The fluorescent lamp includes a tube having a first surface which serves as a substrate. A continuous layer of aluminosilicate sol-gel material having phosphor particles embedded therein is formed on the first surface of the tube. The continuous layer of sol-gel material having phosphor particles embedded therein is formed by first preparing an aluminosilicate sol-gel solution. The phosphor particles are next mixed in the aluminosilicate sol-gel solution to obtain a phosphor particle carrying aluminosilicate sol-gel solution. Then, the first surface is coated with the phosphor particle carrying aluminosilicate sol-gel solution. The phosphor particle carrying aluminosilicate sol-gel solution is dried on the first surface to form a phosphor particle containing sol-gel layer.
