A new way of modulating color emissions from transparent films

(Tokyo University of Science) Transparent luminescent materials have several applications; but so far, few multicolor light-emitting solid transparent materials exist in which the color of emission is tunable. Now, a team of scientists from Japan has developed an unprecedented mechanism to tune the photoemission of a solid polymeric film--controlling the flow of protons in it by applying a voltage. Their study provides fresh insights into the creation of more efficient multicolor transparent lum...
