Abstract
A green light emitting silicate-containing phosphor having both enhanced luminescence intensity and a shortened persistence time and a method for manufacturing the foregoing phosphor can be provided, and a phosphor precursor can also be manufactured by releasing a mixed solution from an exit of the outlet flow passage, after a suspension containing a silicon compound is supplied into the first inlet flow passage, a solution containing a metallic compound for forming a silicate-containing phosphor precursor is supplied into the second inlet flow passage, and the foregoing suspension and solution are introduced into the contact section so as to mix with each other with controlling a flow of the mixed solution so as to keep a Reynolds number of the mixed solution to be 3×10to 1×10.
