Description
技术领域
本发明窄带吸收银/二氧化钛薄膜全息材料及制备方法和应用，属于光学信息存储材料制备领域。
背景技术
能源的高效利用是目前解决的关键问题。作为一种重要的能源，光能的转化已经在光催化，太阳能电池，生物技术和数据存储领域引起了广泛的关注。近年来，大容量的光存储已经成为信息技术的重要需求，可通过全息技术来实现。提高全息存储的速率和效率一直是应用中的热点问题，可以通过优化记录介质的吸收性能来实现。贵金属纳米粒子由于它们的局域表面等离子体共振特性而被用作高效的光电转换介质。光生电子在由贵金属纳米粒子和半导体构成的纳米复合体系中转移，可被用于高性能的纳米器件。在TiO2纳米多孔薄膜中沉积Ag纳米粒子具有优异的热稳定性和颜色调节能力。Ag/TiO2纳米复合薄膜具有与照射光呈现相同的颜色能力，其光致变色行为是与Ag纳米粒子的尺寸和形状相关。在单色光照射下Ag纳米粒子的多样性阻碍了单色光的溶解。虽然紫外还原法、介孔模板法和溶胶-凝胶法得到了广泛的应用，但尺寸均一的贵金属纳米颗粒仍然很难得到，而尺寸均一的贵金属纳米粒子对等离子体在光能量转换中的应用至关重要。
综上，亟需提供一种新方法来改善等离子体纳米粒子较低的单色光灵敏度，以获得高效的全息存储和信息再现，发挥其在光信息处理中的重要作用。

具体实施方式

下述实施例中所用的材料、试剂等，如无特殊说明，均可从商业途径得到。
按照图1所示的流程图制备银/二氧化钛薄膜全息材料。
步骤一、制备二氧化钛薄膜
取TiO2溶胶10mL原液与20mL纯净水放入烧杯中，磁力搅拌至混合均匀，配制出二氧化钛溶液。取P123(PEO20-PPO70-PEO20)嵌段共聚物凝固态1.6g置于另一烧杯中，加入15mL纯净水，长时间(约2h)磁力搅拌至均匀溶解为液态，至此得到造孔剂溶液。将二氧化钛溶液和造孔剂溶液混合，磁力搅拌1h后至混合均匀，取出30mL，而后加入20mL乙醇，保证两者的体积比为3：2即可。将上述得到的TiO2/P123混合溶液置于烧杯中利用提膜机在玻璃衬底上提膜。提膜速度为2cm/s，停留时间为8s。薄膜提出后马上用红外灯照2min～3min，之后放入120℃烘箱烘5min，使二氧化钛薄膜能够固化在玻璃衬底上，重复3次提膜烘烤后，放入电炉加热(温度为500℃)进行退火处理。500℃下P123完全分解挥发，TiO2会围绕其周围形成一个空洞，最终形成利于后续Ag粒子生长的环境，经过退火处理后将二氧化钛薄膜取出置于室内冷却至室温，最终得到稳定无色透明、疏松多孔的二氧化钛薄膜。
步骤二、配制pH值为8.5的单宁酸溶液
在室温下，称取分子量为1701.2的单宁酸0.1361g置于烧杯中，而后加入40mL纯净水，磁力搅拌至均匀溶解，配制出0.009mol/L的碳酸钾溶液，磁力搅拌至均匀溶解，配制成单宁酸溶液和碳酸钾溶液的混合液；通过pH计测定混合液的pH值，调节pH值至8.5，溶液变成墨绿色，稍后将溶液避光保存。
步骤三、制备附着有单宁酸的二氧化钛薄膜
在室温下，将步骤一得到的二氧化钛薄膜浸没在步骤二配制的单宁酸溶液中2h，用锡纸覆盖于培养皿上，使二氧化钛薄膜在避光条件下浸泡，后用镊子将二氧化钛薄膜取出，将其用空气进行吹干，得到附着有单宁酸的淡黄色透明的二氧化钛薄膜。
步骤四、配制硝酸银溶液
称取0.85g的硝酸银固体颗粒，将硝酸银固体颗粒溶入25mL纯净水中置于磁力搅拌器上进行搅拌，搅拌均匀后，将25mL乙醇加入其中，得到透明的硝酸银溶液，其中硝酸银的摩尔浓度为0.1mol/L。
步骤五、水浴加热方法得到银/二氧化钛薄膜
将步骤三中得到的附着有单宁酸的二氧化钛薄膜浸没在经步骤四所配制的硝酸银溶液中，在30℃的水浴中加热10min，二氧化钛薄膜由淡黄色透明变为浅棕色的银/二氧化钛薄膜。
步骤六、可见激光还原法高效的窄带的银/二氧化钛薄膜
将步骤五中得到银/二氧化钛薄膜浸渍于步骤四所配制的硝酸银溶液中，可将激光照(30mW)不同时间促使高浓度银离子的还原，结束后立即用镊子将其取出，利用纯净水对其进行漂洗，将其用空气进行吹干后，得到棕色银/二氧化钛薄膜，即为银/二氧化钛薄膜全息材料，将银/二氧化钛薄膜全息材料采用双层包裹置于黑暗条件下，避光保存，备用；其中双层包裹的内层为擦镜纸包裹，外层为锡纸包裹。
上述方法制备得到的银/二氧化钛薄膜全息材料进行吸收光谱测试与全息存储测试应用，
对银/二氧化钛薄膜全息存储材料进行吸收光谱测试与全息存储测试
(a)利用紫外-可见吸收光谱仪测试经上述步骤得到的银/二氧化钛薄膜全息材料，单宁酸单独作用还原的银/二氧化钛薄膜和激光单独作用还原的银/二氧化钛薄膜的吸收光谱，采用洛伦兹模型对吸收光谱进行拟合，吸收峰与单峰宽的比值R用来表示吸收带的性质；具体请见图2、图3、图4及图5，图2、图3、图4及图5为本发明及对照实验制备的银/二氧化钛薄膜的吸收光谱图和洛伦兹拟合结果。在该图像中，观测吸收曲线的形状及分布，验证本发明制备的银/二氧化钛薄膜全息材料具有强的窄带吸收。
(b)采用以上步骤中得到的银/二氧化钛薄膜全息材料为存储介质，进行蓝光的全息存储。如图6所示，图6为基于本发明制备的银/二氧化钛薄膜全息材料的蓝光全息存储的光栅生长动力学曲线图。此曲线图证实了，本发明提供的方法制备的银/二氧化钛薄膜全息材料适用于蓝光的快速、高效的全息存储。
上述方法制备得到的银/二氧化钛薄膜全息材料进行彩色全息再现应用，通过偏振通道分割彩色信息，得到两幅以上全息图，且每幅全息图的颜色一致；将各幅全息图在所制备的银/二氧化钛薄膜全息材料的同一点通过使用正交圆偏振装置顺序记录，通过引进具有不同颜色和圆偏振态的读出光来实现复合全息图的彩色再现。
如图7所示(详见图7(a)、图7(b)及图7(c))，采用473nm激光作为写入光，物光为右旋圆偏振光，参考光为左旋圆偏振光时记录花形状的图案，物光为左旋圆偏振光，参考光为右旋圆偏振光时记录叶形状的图案。采用532nm和671nm激光作为读出光，偏振态分别右旋圆偏振光和左旋圆偏振光，同时读出红色花和绿色叶的全息图。使用彩色数字相机用于再现彩色全息图。
