The film thicknesses were measured using a profilometer (Talystep, Taylor Hobson, UK) on a scratch made immediately after deposition of five independent measurements on each sample, and found to be in the range of 50 - 10 mm. Fluorescence spectroscopy measurements revealed that PTLSC films are promising candidates for preparing efficient waveguides and for harvesting and concentrating sunlight as presented by the subject of another paper submitted by our group.
