Description
技术领域
本发明涉及光致变色技术领域,具体涉及一种双钙钛矿掺杂银离子光致变色陶瓷粉的制备方法。
背景技术
一些物质在外场(如光场、电场、磁场、热场等)的刺激下能够发生光学性质的变化,其中比较常见的有光致变色、电致变色、热致变色等。其中,因为光场操控具有很好的安全性与易操作性,光致变色近年来受到众多人的关注。
光致变色主要指材料在某个特定波长的光的照射下发生光学性能的变化,从而样品的颜色发生变化。光致变色材料应用于光存储、分子开关,防伪标记等领域;现有技术中,光致变色材料主要分为无机光致变色材料、有机光致变色材料、有机-无机光致变色材料;其中无机光致变色材料因具有更优异的热稳定性、更长的使用循环次数寿命而常用于科学研究,目前主要无机光致变色材料主要包括:过渡金属氧化物(如WO3、TiO2等)、强氧化物(BaMgSiO4、Ca2SnO2等)、铁电体(Na0.5Bi2.5Nb2O9,Na0.5Bi4.5Ti4O15,K0.5Na0.5NbO3等)。近年来,双钙钛矿氧化物作为一种新型的无机材料,在光伏材料、发光材料、光催化等领域显现出瞩目的应用前景,然而,在光致变色领域,无机双钙钛矿氧化物还鲜有相关报道,在双钙钛氧化物中实现明显的光致变色现象,即可以扩展无机光致变色材料的探索范围,为探索性能更好的无机光致变色材料提供了一个新的方向,又可以进一步扩大双钙钛矿氧化物的应用范围。
无机光致变色通常与空位缺陷诱导的色心的形成或者发色团中价电子跳变产生的电荷转移有关。其中色心的形成与材料中的氧空位含量密切相关。较大的氧空位缺陷含量有助于提高材料的光致变色性能。可以通过以下策略增加无机光致变色材料中的氧空位含量:(1)挥发元素的选择,如Ba2+、Mg2+、Ca2+等;(2)高合成温度。合成温度越高,蒸发的金属阳离子越多,为了维持电荷平衡,基质中的氧空位含量越高;(3)掺杂低价元素,然而并非是所有低价元素的掺杂都能实现氧空位的增加。
因此,为了解决上述问题,本文提出了一种双钙钛矿Ba2LaNbO6掺杂银离子光致变色陶瓷粉的制备方法。首先,Ba元素的存在可以产生更多阳离子缺陷,同时,铌酸盐通常需要较高的烧结温度,最后,选择银离子作为低价元素来作为掺杂元素。通过以上方法来增加双钙钛矿Ba2LaNbO6中的氧空位含量,从而在双钙钛矿氧化物中实现明显的光致变色现象。
发明内容
本发明的目的在于提供一种双钙钛矿Ba2LaNbO6掺杂银离子光致变色陶瓷粉的制备方法,利用高温固相烧结,以在双钙钛矿氧化物Ba2LaNbO6中实现明显的光致变色现象。
为实现上述技术目的,达到上述技术效果,本发明是通过以下技术方案实现:
一种双钙钛矿Ba2LaNbO6掺杂银离子光致变色陶瓷粉的制备方法,包括如下步骤:
S1:将高纯的BaCO3、La2O3、Nb2O5和Ag2O进行研磨混匀得到混合粉料A;
S2:将步骤S1所得混合粉料A置于温度为1350℃、空气气氛中高温烧结6h,自然冷却到室温后,研磨得到Ba2LaNbO6:Ag+光致变色陶瓷粉末;
进一步的,所述步骤S1中的混合粉料A中掺杂离子Ag+(Ag2O),浓度以mol百分比计,其中Ag+占1~4mol%。
进一步的,本发明制备的Ba2LaNbO6:Ag+原始状态为白色,当表面受到波长为365nm的紫外光照射一定时间后,受到辐照范围内的陶瓷粉表面区域将变成具有显著区分度的粉色。
本发明的有益效果:
本发明提出的一种双钙钛矿Ba2LaNbO6掺杂银离子光致变色陶瓷粉的制备方法,得到光致变色无机双钙钛矿Ba2LaNbO6:Ag+陶瓷粉;本发明Ba2LaNbO6:Ag+光致变色材料在紫外激发下具有优异的光致变色性能;通过低价Ag+离子掺杂解决无机双钙钛矿氧化物Ba2LaNbO6光致变色浅的问题:增加氧空位含量,从而有助于实现光致变色效应。同时扩展了无机光致变色材料的探索范围与双钙钛矿氧化物的应用范围。
本发明Ba2LaNbO6:Ag+光致变色陶瓷粉在经过365nm紫外灯的照射下能够快速地由白色变为深粉色,本发明Ba2LaNbO6:Ag+光致变色材料在紫外激发下具有优异的光致变色性能,在应用于信息存储和防伪标识等领域时具有优越的性能前景。
本发明中控制掺杂离子Ag+(Ag2O)的浓度以mol百分比计,可以实现对光致变色材料的优化调节,并提高了材料的稳定性和光致变色效果的可控性,从而获得更好的光致变色效果和性能。传统的光致变色材料在长期使用过程中存在稳定性问题,容易发生退色或失去光致变色能力。而通过掺杂银离子,可以增加双钙钛矿Ba2LaNbO6中的氧空位含量,提高材料的稳定性。氧空位的存在能够增强材料的电子传导性能,并减少电子的再组合速率,从而延长光致变色材料的使用寿命。
双钙钛矿Ba2LaNbO6掺杂银离子光致变色陶瓷粉具有广泛的应用潜力。防伪标识方面,该材料具有明显的颜色变化特性,可以用于制作防伪标记,提高产品的安全性和可辨识性;在传感器领域,该材料的光致变色特性可以用于制作光学传感器,实现对环境参数的快速检测和监测;在光学存储和显示材料方面,该材料可以用于制作高密度的光学存储介质和高分辨率的显示器件,提高存储和显示的效果。该材料不仅具有较高的热稳定性和使用寿命,还能实现明显的光致变色效果,为其在各个应用领域的推广提供了可靠的基础。
当然,实施本发明的任一产品并不一定需要同时达到以上所述的所有优点。

一种双钙钛矿Ba2LaNbO6掺杂银离子光致变色陶瓷粉的制备方法,具体步骤如下:
S1:将高纯的BaCO3、La2O3、Nb2O5和Ag2O进行研磨混匀得到混合粉料A;
S2:将步骤S1所得混合粉料A置于温度为1350℃、空气气氛中高温烧结6h,自然冷却到室温后,研磨得到Ba2LaNbO6:Ag+光致变色陶瓷粉末;
所述步骤S1中的原料BaCO3、La2O3、Nb2O5和Ag2O按2:1:1的化学计量比称量,混合粉料A中掺杂离子Ag+(Ag2O),浓度以mol百分比计,其中Ag+占1~4mol%;
本发明制备的Ba2LaNbO6:Ag+原始状态为白色,当表面受到波长为365nm的紫外光照射一定时间后,受到辐照范围内的陶瓷粉表面区域将变成具有显著区分度的粉色。
实施例1
如图1所示
将本申请获得的样品进行X射线衍射分析,得到X射线衍射图,如图1所示,从图中可以看出该系列样品掺杂不同浓度Ag+后的衍射峰均与Ba2LaNbO6标准卡片PDFNO.37-0856匹配,说明该系列样品均为Ba2LaNbO6相;
纯相表示样品中只存在这种化合物,这意味着该系列样品中Ag+离子成功进入Ba2LaNbO6晶格中,即不存在与Ba2LaNbO6不同的化合物或杂质,所以通过本申请获得样本取得的效果,能够准确评估Ba2LaNbO6:Ag+的特性和性质。
实施例2
如图2所示,探究了不同浓度Ag+掺杂对Ba2LaNbO6陶瓷粉光致变色性能的影响。

将本申请获得到样品通过365nm紫外光辐照2min,测得Ba2LaNbO6、Ba2LaNbO6:1mol%Ag+、Ba2LaNbO6:2mol%Ag+、Ba2LaNbO6:4mol%Ag+陶瓷粉变色前后的漫反射光谱,如图2所示,可以看出,样品在365nm紫外灯照射2min后,漫反射光谱在400nm-800nm范围内的强度降低,结果显示,掺杂2mol%Ag+离子后,Ba2LaNbO6:Ag+陶瓷粉变色效果最好。
实施例3
如图3、4所示
通过掩膜版的覆盖,在365nm紫外灯的照射下,可以实现光质变色图案的写入。
如图3所示为Ba2LaNbO6:Ag+陶瓷粉变色前的照片,陶瓷粉的颜色主要为白色。通过掩膜板遮盖,在365nm紫外灯的照射下,可以明显发现样品由白色变为粉色。
本发明所得的Ba2LaNbO6:Ag+陶瓷粉,其中烧结温度为1350℃时,烧结时间为6h,得到具有光致变色效应的无铅双钙钛矿氧化物,并且光致变色现象显示出响应速度快、对比度高的优点。说明具有光致变色特点的银离子掺杂的Ba2LaNbO6双钙钛矿氧化物在光开关、光存储以及光学探测器等方面具有广泛的应用前景。
以上公开的本发明优选实施例只是用于帮助阐述本发明。优选实施例并没有详尽叙述所有的细节,也不限制该发明仅为所述的具体实施方式。显然,根据本说明书的内容,可作很多的修改和变化。本说明书选取并具体描述这些实施例,是为了更好地解释本发明的原理和实际应用,从而使所属技术领域技术人员能很好地理解和利用本发明。本发明仅受权利要求书及其全部范围和等效物的限制。
