Abstract
The integration of reversible photochromism and multicolor luminescence modulation in transparent glass offers significant potential for high-capacity, nonvolatile 3D optical storage. However, achieving effective multicolor luminescence modulation and 3D patterning remains a challenge. This study introduces a Mn2+/Sb5+ charge compensation mechanism to induce purple photochromism in gallium silicate glass via the Mn2+ → Mn3+ transition under 532 nm laser irradiation. The effect is fully reversible, with efficient thermal erasure. By codoping Tb3+ and Mn2+, wavelength-independent red and green luminescence modulation enables multidimensional optical encoding. Arbitrary 3D photochromic patterns are directly inscribed using a 532 nm laser and decoded via tunable luminescence. This multimodal system advances 4D optical storage by combining 3D spatial dimensions with tunable luminescence intensity multiplexing. Mn2+/Tb3+ doped gallium silicate glass represents a breakthrough for 3D information display, data encryption, and insights into photochromic mechanisms in transition-metal-doped photonic systems.
