Abstract
An evaporation crucible and an evaporation system are disclosed. The evaporation crucible includes a crucible body and at least one nozzle located on a top face of the crucible body. The crucible body includes an inner wall and an outer wall that are bonded together, where the inner wall is formed of a first material, the outer wall is made of a second material, and a heat conductivity of the first material is larger than that of the second material. The evaporation crucible and the evaporation system may solve technical problem of non-uniform evaporation of vapor deposition material in prior arts, such that a uniform coating on OLED substrate may be achieved.
