Phosphor fluorescence

WebThis strategy enables the transformation of rigid perovskite quantum dot glass into flexible luminescent film materials, and further improved the fluorescence quantum yield (PLQY) from 50.5% to 70.2%. The flexible film has good tensile property, and its length can be strained 5 times as long as the original length. WebA phosphor is a material that luminesces when exposed to a stimulating radiation. Often there is a matrix, for example ZnS and an activator. Examples of activators are silver in ZnS:Ag or copper in ZnS:Cu. The activator concentration in the matrix can be less than 0.01% in some systems up to well over several percent in others.
