Высокотемпературная люминесценция кристаллов ZnSe:Yb

The problem of obtaining of effective edge luminescence with high temperature stability in the zinc selenide crystals is discussed. This task is solved by using as the dopant rare-earth element yttrium, which is introduced into the undoped ZnSe crystal by diffusion method. Doping was carried out in...

This task is solved by using as the dopant rare-earth element yttrium, which is introduced into the undoped ZnSe crystal by diffusion method. Doping was carried out in an evacuated to 10–4 Torr and a sealed quartz ampoule, in the opposite ends of which is a sample and a mixture of the crushed Yb and Se.

Исследовано влияние иттербия на люминесцентные свойства беспримесных кристаллов селенида цинка. Показано, что в спектрах излучения образцов ZnSe:Yb наблюдается только голубая полоса, имеющая экситонную природу и обладающая высокой температурной стабильностью.
