The effect of luminescent powder (LP) type and characteristics on the properties of architectural luminescent glass-mortars (ALM) was investigated. Four LPs including ZnS:Cu (LP₁) and SrAl₂O₄:Eu²⁺,Dy²⁺ (LP_2-4) with different particle sizes and surface conditions (with or without a protective layer) were coated on the surface of glass particles using an adhesive paint for producing luminescent glass (LG). LG was then used to replace coarse aggregate in conventional glass mortar for the production of ALM. The results showed that all ALMs obtained good fresh properties and mechanical strength (>40 MPa) with proper excitation and emission wavelengths ranging from 250 to 450 nm and 500–560 nm, respectively, demonstrating the feasibility of fabricating decorative concrete. Regarding the glow light performance, SrAl₂O₄:Eu²⁺,Dy²⁺ outweighed ZnS:Cu in all luminescent indexes including initial brightness (luminescent intensity), decay rate, and afterglow time. Coarser LP attained lower luminescent intensity but a better decay rate due to the its relative lower specific surface area. A protective layer on the LP surface (surface condition) inhibited its light absorption and emission capacity, leading to poor luminescent performance. The adhesive paint used for producing LG, having poor UV aging resistance, was susceptible to sunlight degradation, reflected by colour turning into brown. The darker colour reduced its light transmitting efficiency, inducing a decrease in glow light performance of ALM. The excellent water and wearing resistance of ALM allowed maintaining their luminescent performance under extreme environment conditions.

研究了发光粉（LP）类型和特性对建筑发光玻璃砂浆（ALM）性能的影响。四种 LP 包括 ZnS:Cu (LP ₁ ) 和 SrAl ₂ O ₄ :Eu ²⁺ ,Dy ²⁺ (LP _2-4) 具有不同粒径和表面条件（带或不带保护层）的玻璃颗粒表面涂有用于生产发光玻璃 (LG) 的粘合剂涂料。然后用 LG 代替传统玻璃砂浆中的粗骨料来生产 ALM。结果表明，所有ALMs都获得了良好的新鲜性能和机械强度（> 40 MPa），适当的激发和发射波长分别为250-450 nm和500-560 nm，证明了制造装饰混凝土的可行性。关于辉光性能，SrAl ₂ O ₄ :Eu ²⁺ ,Dy ²⁺在包括初始亮度（发光强度）、衰减率和余辉时间在内的所有发光指标中都超过了 ZnS:Cu。较粗的 LP 获得较低的发光强度，但由于其相对较低的比表面积而具有更好的衰减率。LP表面的保护层（表面状态）抑制了它的光吸收和发光能力，导致发光性能差。用于生产 LG 的胶粘剂涂料抗紫外线老化性能较差，易受阳光降解，表现为颜色变为棕色。较深的颜色降低了其透光效率，导致 ALM 的辉光性能下降。ALM 优异的耐水性和耐磨性使其能够在极端环境条件下保持其发光性能。
