A method for coating a fluorescent lamp with an aqueous suspension of a multi-component phosphor blend wherein the isoelectric point(IEP) of at least one of the individual phosphors is separated by at least two pH units from the effective IEP of the other phosphors. The method involving altering the IEP of the first phosphor to within about two pH units of the effective IEP of the other phosphors, adding the modified phosphor to an aqueous suspension of the other phosphors, the aqueous suspension having a pH outside the range defined by the modified IEP and the effective IEP to inhibit flocculation, and coating a fluorescent lamp.
