Initially, Brown Perovskite obtains different colors because the light is specially broken in nanoyapics created. This principle is similar to a mechanism that creates a bright color on the wings of the butterflies. Scientists were able to control not only color, but also other optical features of the material.
As explained by the experts, the direction of the light to spread depends on the decoration. This allows you to create light sources with controlled brightness without changing the main properties of the material.
An important advantage of the method is the speed and purity of the process. Laser application of patterns does not leave damage and burning.
