QDot™ Perovskite Cs4PbBr6 powder represents a composite material that consists of Perovskite CsPbBr3 Quantum Dots that are embedded into transparent C4PbBr6 matrix called zero-dimensional perovskite phase. The optical properties are similar to CsPbBr3 QDs (emission peak 515 nm, FWHM<25 nm, PLQY up to 70-80 %), but because this materials is encapsulated with Cs4PbBr6 phase, it shows exceptional stability. This makes him very promising for light conversion technologies as a remote phosphors for lighting applications or others. This material is in the powder form with µm size particles. QDot™ Perovskite Cs4PbBr6 powder is chemically robust and can withstand the temperature up to 180  C in air for several hours. Because of the encapsulation matrix, 4-5 times more concentration of the material is required than genuine CsPbBr3 QDs to achieve the same light intensity.
