由於鈣鈦礦材料具有優異的光學性質與簡易製備的優勢，因此現今被廣泛應用於光學元件的研究，然而鈣鈦礦極容易受到空氣中的水氧值影響，產生降解，因此封裝的重要性也由此體現。
本研究以薄荷醇 (menthol) 和1-十四醇 (1-tetradecanol) 配製深共熔溶劑 (Deep Eutectic Solvent ,DES)，並利用此疏水性溶劑作為鈣鈦礦前驅溶液的反溶劑，探討鈣鈦礦在該溶劑中的結晶尺寸與形貌。隨後，在深共熔溶液系統中加入丙烯酸 (Acrylic Acid ,AA) 和丁酸 (Butyric Acid ,BA) 作為複合材料的聚合單體，並添加二苯基-(2,4,6-三甲基苯甲酰)氧磷 (TPO) 作為光起始劑 (photoinitiator)，以及聚乙二醇甲醚甲基丙烯酸酯 (PEGMA) 作為交聯劑，開發出一款可以用一鍋法製備的光固化深共熔凝膠漿料，並將鈣鈦礦奈米結晶摻雜於其中。
藉由配方調整，可調控凝膠之機械性質實現超過 700 % 的形變量，同時不影響材料之光學性質。將鈣鈦礦材料封裝於深共熔凝膠中，使材料具備鈣鈦礦優異的光學性質，還可在大氣中進行長期保存。在 25 °C、濕度 30 % ～ 40 % 的環境下，該材料可穩定保存超過 30 天，仍能達到 77.8 % 的光致發光強度。此外，該複合材料可應用於光固化 3D 列印技術，進一步拓展其多樣化應用。

Due to the excellent optical properties and ease of fabrication, perovskite materials have become widely studied for optical devices. However, perovskites are highly susceptible to degradation caused by moisture and oxygen in the air, highlighting the importance of encapsulation.
In this study, menthol and 1-tetradecanol were used to formulate a deep eutectic solvent (DES), which served as an anti-solvent for the perovskite precursor solution. The crystallite size and morphology of the perovskite in this solvent were investigated. Subsequently, acrylic acid (AA) and butyric acid (BA) were introduced as monomers for composite material polymerization in the DES system, with diphenyl(2,4,6-trimethylbenzoyl)phosphine oxide (TPO) used as the photoinitiator, and poly(ethylene glycol) methyl ether methacrylate (PEGMA) as the cross-linker. A one-pot photocurable deep eutectic solvent-based gel paste was developed, into which perovskite nanocrystals were doped.
By adjusting the formulation, the mechanical properties of the gel were tuned to achieve a strain capacity exceeding 700 % without compromising its optical properties. Encapsulating the perovskite within the DES gel allowed the material to retain the perovskite's outstanding optical properties and maintain long-term stability in ambient conditions. At 25°C and 30 % - 40 % humidity, the material remained stable for over 30 days, retaining 77.8 % of its photoluminescence intensity. Furthermore, this composite material is suitable for photocurable 3D printing technology, expanding its potential applications.
