A phosphor layer comprising a phosphor plate adhesively formed by a phosphor powder and an adhesive agent. The phosphor plate has a front side and a back side. The phosphor layer also has particles which are fixedly connected to the front and/or back side of the phosphor plate. Also provided in the present invention are a phosphor component, a corresponding light source, a projection system, and a method for manufacturing the phosphor layer. The phosphor component prevents adhesion between the phosphor plate and substrates thereof in high temperature conditions. A manufacturing method for the phosphor layer includes forming a phosphor plate by adhesively fixing a phosphor powder by an adhesive agent, the phosphor plate having a front side and a back side, and fixedly connecting at least one particle to the front and/or back side of the phosphor plate.
