- Abstract
Nanodimensional structures based on zinc and cadmium sulfides and doped with Mn, Cu, and Eu ions have been synthesized by the method of appearing reactants in a polymerizable medium. The broadband PL of synthesized compositions is related to recombination processes on the defect levels of semiconductor structures. Narrow PL bands appear due to electron transitions between energy levels of Eu3+ ions. The PL is excited due the interband transitions and electron transitions to levels of structural defects, as well as due to intrinsic absorption and energy transfer to Eu3+ ion levels.
