Abstract: A low observable photoluminescent tracer projectile, for use with a small caliber weapon at night—which utilizes a base phosphor material of Ca, Sr and S, or a base phosphor material of Y2, O2, and S—with a combination of minor dopant ingredients; which base phosphor material is mixed with a clear binder to form a photoluminescent material which is applied to the rear end, or base, of a small arms projectile as a thin layer; to which thin layer is added a layer of small retro-reflectors—whereby, when this projectile is fired from the weapon, the photoluminescent mixture will be activated and will be observable, using night vision at an angle of 0 to about 20 degrees from the rear end of the projectile.
