Luminous stone gardening fish tank landscaping pebbles artificial Main raw materials: Rare earth long afterglow luminous powder, polystyrene resin 1 luminous powder It is a high-tech self-luminous product activated by rare earth metal elements in alkaline earth aluminate and silicate. The temperature resistance reaches about 800 degrees. Its function is to absorb light, store light and emit light, absorb light in bright places (more than half an hour), and emit light in dark places. It has a strong ability to absorb short-wave visible light with a wavelength below 450 nanometers. By absorbing all kinds of natural light or artificial light, it can realize the self-luminous function in the dark state, and it can be recycled infinitely. The initial high brightness of the luminescent material can reach More than 2-3 hours, the shoulder luminous curve is gentle, and the afterglow lasts for more than 8-10 hours. 2.
