Yellow-green luminous powder is a light-storing self-luminous pigment mainly composed of rare earth aluminate. It appears as light yellow/pale green powder in daylight, emits bright and soft yellow-green light (520-530nm) in the dark after absorbing light. It is the mainstream type with the highest brightness, longest afterglow and most sensitive to human eyes among all luminous colors, environmentally friendly, non-toxic and non-radioactive.
