Popis:	Depending on growth and annealing conditions ZnO crystals can show a reddish coloration clearly deviating from the normal, colorless transparency. The additional broad nearedge absorption is observed when particles of few nanometer diameter are present in the crystals. Excitation of plasmons in Zn nanoparticles can explain this absorption.
