A facile approach for possible industrial production of long-persistent phosphorescence, continuing to emitting light for a long time period, smart cobbles were developed toward photoluminescent hard surfaces. The inorganic strontium aluminium oxide pigment doped with rare earth elements was added to a synthetic organic epoxy in the presence of polyamine as a hardener to make a phosphor-loaded viscous fluid that can then be hardened in a few minutes. The transparency of the solid cobbles can be accomplished easily using homogeneous dispersion of the phosphor in the epoxy resin fluid before the addition of a hardener to avoid pigment aggregation. This pigment-epoxy formula can be easily applied industrially onto flagstones surfaces under ambient conditions. The photoluminescent cobblestones demonstrated an optimum excitation wavelength at 366 nm and an emission band at 521 nm with a long-persistent phosphorescence cobble surface. The development of a translucent white colour under normal daylight, bright green under ultraviolet (UV) irradiation, bright white colour after 30 sec in the dark, and phosphorescent green colour after 75 min in the dark was indicated using Commission Internationale de l'Eclairage (CIE) Laboratory coloration measurements. The luminescent hard composite cobble exhibited a highly durable and reversible long-persistent phosphorescence light. Photoluminescence, morphological, and hardness properties as well as the elemental composition of the prepared cobbles were explored.

对于可能的工业生产,长时间持续发出磷光,并持续长时间发光,一种简便的方法是向光致发光的硬表面开发了智能鹅卵石。在多胺作为硬化剂的情况下,将掺杂有稀土元素的无机锶铝氧化物颜料添加到合成有机环氧树脂中,制成负载磷光体的粘性流体,然后可以在几分钟内将其硬化。使用荧光粉在环氧树脂流体中的均匀分散,然后添加硬化剂以避免颜料聚集,可以轻松实现固体小卵石的透明性。这种颜料-环氧配方可在环境条件下轻松地工业应用到石板表面上。这些光致发光的鹅卵石显示出最佳的激发波长在366 nm,发射带在521 nm处具有持久的磷光性鹅卵石表面。使用国际照明委员会(Commission Internationale de l'Eclairage( CIE)实验室着色测量。发光的硬质复合材料鹅卵石显示出高度耐用且可逆的持久性磷光。探索了制备的鹅卵石的光致发光,形态和硬度特性以及元素组成。使用国际照明委员会(Commission Internationale de l'Eclairage( CIE)实验室着色测量。发光的硬质复合材料鹅卵石显示出高度耐用且可逆的持久性磷光。探索了制备的鹅卵石的光致发光,形态和硬度特性以及元素组成。使用国际照明委员会(Commission Internationale de l'Eclairage( CIE)实验室着色测量。发光的硬质复合材料鹅卵石显示出高度耐用且可逆的持久性磷光。探索了制备的鹅卵石的光致发光,形态和硬度特性以及元素组成。闪蒸(CIE)实验室着色测量。发光的硬质复合材料鹅卵石显示出高度耐用且可逆的持久性磷光。探索了制备的鹅卵石的光致发光,形态和硬度特性以及元素组成。闪蒸(CIE)实验室着色测量。发光的硬质复合材料鹅卵石显示出高度耐用且可逆的持久性磷光。探索了制备的鹅卵石的光致发光,形态和硬度特性以及元素组成。
