Cathode-ray tube and blue phosphor |
摘要 |
In a cathode-ray tube, a phosphor screen is formed by employing a blue phosphor obtained by mixing Cu with ZnS:Ag, Al in a normal solid phase reaction, then forming the phosphor solution on the inner surface of a panel of a cathode ray tube. The resulting cathode-ray tube can have increased brightness with negligible loss of chromacity. The amount of Cu as a co-activator in the blue phosphor can range between 0.6 to 1.5 ppm. In a preferred embodiment, the blue phosphor has a chromacity y-value of 0.089.
