Highly orientated polycrystalline ZnO films with hexagonal structure have been deposited on Si substrate by rf magnetron sputtering. Strong monochromatic green emission located at 490 nm has been observed when excited with 300 nm light at room temperature (RT). The photoluminescence (PL) intensity decreases with increasing oxygen pressure during film deposition and it increases by thermal annealing...
Polycrystalline ZnO films with good orientation were deposited on sapphire, quartz, Si and 7059 glass substrates by r.f. magnetron sputtering. A strong UV photoluminescence (PL) peak (located at 356nm) and a weak blue emission peak (located at 446nm) were observed at room temperature (RT) for the films deposited on sapphire, quartz and Si substrates when excited with 270nm light. For the films prepared...
