Abstract: A method that provides a new way to embed rare earth fluorides into silicate (or germania-doped silica) glasses by means of solution chemistry. Embedding rare earth fluorides into a silicate (or germania-doped silica) glass comprises the following steps. First, form a porous silicate core preform. Second, submerge the preform into an aqueous solution of rare earth ions. Third, remove the preform from the solution and wash the outside surfaces of the preform. Fourth, submerge the preform into an aqueous solution of a fluorinating agent to precipitate rare earth trifluorides from the solution and deposit in the pores or on the wall of the preform. This is followed by drying.

Abstract: A process for producing a glass product having .DELTA.n, the difference between the central and peripheral portions of the glass, greater than 0.04. This process utilizes a porous glass body which is produced via a phase separation technique. A dopant selected from the group consisting of (1) TlNO.sub.3, (2) TlNO.sub.3 and an alkali metal compound and (3) TlNO.sub.3, Pb(NO.sub.3).sub.2 and an alkali metal compound is then permeated into the micropores of the porous glass product. A concentration gradient of the dopant is then formed by leaching out a portion of the dopant from the micropores. After the dopant is solidified in the mircopores, the porous glass product is dried. A heat-treatment step then serves to collapse the micropores. A glass product having a gradient of refractive indices is therby obtained.
