Photoluminescence Devices
ZnS doped with Mn (ZnS:Mn) can be deposited onto glass and polymeric materials using no substrate heating or post deposition annealing. When excited by a UV light source the coatings are seen to emit bright photoluminescence (PL) with a peak intensity at approximately 600 nm, close to the characteristic emission of Mn phosphor.
- With 0.6 wt.% Mn in the Zn target, measured PL intensities are substantially higher than those attainable using RF magnetron sputtering.
- Deposition rate of 55 nm/min, over an order of magnitude faster than that attainable using conventional RF magnetron sputtering.
