Charge-space dual effects inducing Eu2 +-Ce3 + ions occupancy luminescence in NaSiAlO4 constructed by waste glass coupled aluminum air batteries byproduct Al(OH)3

To explore new approaches for converting solid waste into function materialization, this study investigates that the occupational luminescent structures were constructed by waste glass slag coupled with aluminum-air batteries byproduct Al(OH)₃ through glass relaxation crystallization from molten state. Self-skeleton ion Al³ ⁺ ions and additional skeleton ion B³ ⁺ ions replacing partial Si⁴ ⁺ ions for constructing excellent luminescent structure units. The substitution of Si⁴ ⁺ ions by Al³ ⁺/B³ ⁺ ions intensifies lattice distortion and local structural charge rearrangement, triggering charge-space dual effects inducing Eu²⁺-Ce³ ⁺ ions’ selective occupation luminescence. When Al³ ⁺/B³ ⁺ ions replaced Si⁴⁺ ions, the luminescent intensity of the material increased by 30.67 %/40.83 %. By introducing waste glass slag and aluminum-air battery byproduct Al(OH)₃ as substitute, it was achieved for high-value-added materialization application. The optimal content of substitution slag is 20 %, with the target material’s ∆E = 0.378 eV, demonstrating good thermal stability.
