The adhesive force of phosphor powder layers applied to glass substrate has been examined by centrifugal method. The substrate surface cleanliness and roughness have shown little effect on the adhesive force. However, the adhesive force decreases significantly when the glass substrate has been coated with SnO<SUB>2</SUB> which is used for rapid start fluorescent lamps to give a surface electric conductivity.<BR>The major finding of this report is that the adhesive force on both substrates is strengthened by the addition of fine phosphor or calcium pyrophosphate powder, alkoxides of boron, tin, aluminum or titanium, or silicone oil. Especially, the addition of silicone oil has shown another feature of slight increase in fluorescence intensity.
