ABSTRACT

                                  The Nano-filtered sun spectra colours of the films TiO2 and next the film TiO2  plus Yellow Colour were recorded for a comparative study. 

DETAILS

                The Nano-filtered spectra is a genuine new study hereto not reported in literature. The Nano-coated plastic film  transparent in the bright Sun-Light gives immensely interesting spectra. The record is made in the morning time when Sun rays are straight forward incident on the plastic film coated on two parts one pure TiO2 and the other with TiO2 plus the Yellow Colour. Contrasting pictures reveal outstanding features.

and TiO2 plus the Yellow Colour.

                The spectrum of TiO2 coating reveals the bright  blue and very faint yellow and finally the bright red colours.

Fig.3 WP_20170807_17_04_35_Pro2

                     This spectrum of TiO2 and the Yellow Colour coating, reveals the faint blue, with faint green and contrastingly bright yellow with mesmerizing orange and the red colours.

                   The Sun spectra recorded direct shows the spattered spectrum of all the seven bright colours of the VIBGYOR. The bright Sun light has smeared out the details of the solar spectrum considerably. 

RESULTS:

                      The significant result is that plastic film transparent in the centre shows the bright sun light. But the spectra for the two cases one with just TiO2 coating and the other with TiO2 plus the Yellow Colour significantly different. Mesmerizing Orange colour appears in the second case of TiO2 and the Yellow Colour. The spectral wavelengths could easily be gauged out. Spread out of the colours was a consequence of the slit width which is very high, chosen so that the spectral features become very much evident.

Thank  U. I am retired but active. 

I have an abstract and a paper.

Perhaps U would accept it.

I don’t think I can a trip to your Place.
