Artificial stone and formation therefor

摘要

To provide a further improvement of luminescence performance such as an extension of a continuation time of a light accumulation luminescence or a luminescence by ultraviolet rays, by a control of the structure of the artificial stone. A noctilucent/luminescent artificial stone including a transparent aggregate, at least one kind of a light accumulation material and a luminescent material by ultraviolet rays along with a resin is characterized by that the luminescence performance of the artificial stone is higher than that of the included light accumulation material or luminescent material by ultraviolet rays per se.
