Laser screen for a cathode-ray tube and method for making same |
摘要 |
In a laser screen for a cathode-ray tube having a semiconductor member of a semiconductor compound positioned between a partly transparent mirror and a reflecting mirror, an intermediate member is grown by deposition from vapor phase on the partly transparent mirror. The intermediate member is made of a semiconductor material transparent for radiation generated by the screen and has a bandgap width which is at least 0.98 times as great as the bandgap width of the material of the semiconductor member. The intermediate member is cemented to a transparent heat removing support member.
