Short Answer: Glow in the dark stones from All It Glows harness a unique photoluminescent technology. These stones absorb photon-based light energy and then emit it gradually at a lower wavelength, creating a prolonged luminous effect. Detailed Answer: All It Glows products are ingeniously crafted using a special photoluminescent crystalline compound known as SrAl2O4. This compound exhibits a remarkable ability to absorb light energy, specifically photons. Through a fascinating process, these absorbed photons are subsequently released over an extended duration, culminating in the signature radiant glow of It Glows products. During this mesmerizing transformation, no heat is generated, making it distinct from processes like cold fusion, yet equally captivating. The color of the emitted glow is influenced by the quantity of oxygen molecules within the compound. Oxygen's presence subtly adjusts the crystal field arrangement, leading to variations in the emitted wavelength during the glowing phase: Green SrAl2O4: Emission at 520nm Aqua SrAl2O7: Emission at 480nm Blue SrAl2O19: Emission at 420nm Experience the enchantment of All It Glows products as they illuminate your surroundings with their enduring and captivating luminosity.
