Abstract :
Basic experimental results of the SrTiO3:Pr,Al,Ga phosphor degradation are presented. Especially, based on the AES and XPS results it is understood that the prolonged low voltage and high current density of electron beam cause the characteristic change formed on the phosphor surface ((1) Accumulation of the overlaying carbon, (2) Damage of the crystal structure), being responsible for the rapid degradation of low voltage CL of the SrTiO3:Pr,Al,Ga phosphors
