It is shown experimentally that it is possible to excite rare‐earth and transition metal ions included in aII‐VIcompound matrix as fluoride molecules by direct, hot‐electron impact. Electron‐hole pairs in the matrix are unnecessary and even undesirable. AC excitation of a thin film structure has given external power conversion efficiency of about 10−4at several optical frequencies including the 5480‐Å line of Tb3+.
