Looking for a better solution, the researchers sought lessons from nature. Mimicking themotheye, the new film contains tiny dimples, each 100 nanometres across - about 1,000th the width of a human hair - which cut down reflection. <\/p>\n
A self-assembly technique developed by the scientists was used to produce the nanospheres with the required high level of precision. <\/p>\n
Co-author Guanjan Tan, another member of the Florida team, said: \"Although it is known thatmoth-eye structures can reduce surface reflection, it is relatively difficult to fabricate an anti-reflection film with this nanostructure that is large enough to use on a mobile phone or tablet. <\/p>\n
\"Because the structures are so small, a high-resolution and high-precision fabrication technique is necessary.\" <\/p>\n
Tests showed that viewed in sunlight, glass covered with the film exhibited a more than four-fold improvement in \"contrast ratio\" - the different between the brightest white and darkest black. <\/p>\n
