Multiexcitation of phosphors. additional scattering layer around the chip and special re- flecting medium were proposed to improve the luminous efficiency and color properties of LED devices. LED devices with an n-UV Ga(In)N chip as well as blue GaN chip and multiexcited phosphors were developed and created. These LEDs for white light generation show better quantum yield of green and ... https://cosmeticssquadets.shop/product-category/cocktail-shakers/
