(Zn,Cu)O Photocatalytic Material and Znga2o4: Eu3+ Phosphors
Zinc oxide, an important II–IV semiconductor with direct band gap (3.2 eV ) and large exciton binding energy (60 meV ), has become one of the most attractive materials in research due to its wide application ranging from optoelectronic , (photo)catalysis  and devices for optic  or biology  together with its peculiar properties of good stability, bio-compatibility and non-toxicity. The control over the size and morphology of nanometer micrometer-sized ZnO crystals represents a great challenge for the design of novel functional devices. Doping with selective elements (generally transition metal ions), also offers an effective method to adjust the electrical, magnetic and optical properties of zinc oxide.
