In the demonstration, the team used metamaterials having hyperbolic dispersion to enhance the light emission properties of the nanocrystals and simultaneously engineered an efficient light extraction scheme. (sciencedaily.com)
Since different semiconductor crystals typically have different lattice constants, layer - by - layer growth of different semiconductors will cause defects, stress, and ultimately bad crystals, killing light emission properties.» (sciencedaily.com)
They also confirmed the phosphor's predicted light absorption and emission properties in the lab. (sciencedaily.com)
