Different from the quenching effect of conventional dyes, aggregation-induced emission (AIE) dyes radiate fluorescence with the increase of aggregation state, which is a new application in optical storage. In order to increasing the fluorescence contrast of information recording point, a higher writing beam is required. It means that the fluorescence contrast of information point is not excellent at low writing laser power, which undoubtedly improves the bit error rate of information readout. To circumvent the above problem, we doped Mg^{2 +} ions in tetrastyrene (TPE) resin and found that its fluorescence intensity was enhanced. Under this feature, we use the same writing power and find that the fluorescence contrast of its information is also significantly enhanced. Our results provide a way to realize super-resolution recording for AIE optical storage, and to explore the use of AIE dye doped photopolymers chemical sensors.
