WebThe first one is the long-lasting glow in the dark powder also known as strontium aluminate powder, for it is made from rare earth and strontium aluminate. It is non-toxic and non-radioactive to human, featuring high brightness and very long afterglow time.
Strontium aluminate phosphors produce green and aqua hues, where green gives the highest brightness and aqua the longest glow time. Different aluminates can be used as the host matrix. This influences the wavelength of emission of the europium ion, by its covalent interaction with surrounding oxygens, and crystal field splitting of the 5d orbital energy levels. The excitation wavelengths for strontium aluminate range from 200 to 450 nm, and the emissio…
