Abstract
A CRT device for generating a bright green light spot is shown. The device employs a terbium activated phosphor. Troublesome radiations emitted by the phosphor particularly in the 586 nm region are significantly decreased without significant decrease of the desired 544 nm radiation by use of a concentrated solution of a soluble praseodymium salt.
