Description

激光玻璃中稀土猝灭浓度的预测方法、装置和计算机设备 技术领域
本公开涉及玻璃材料技术领域,尤其涉及一种激光玻璃中稀土猝灭浓度的预测方法、装置和计算机设备。
背景技术
玻璃材料是一种应用极其广泛的无机物材料,除被应用于常见的日用、建筑、化工、医疗等领域之外,玻璃材料还在电子信息、国防军工、交通能源等众多高精尖技术领域得到广泛应用。激光玻璃是一种以玻璃为基体材料的固体激光材料,是固体激光器和光纤激光器的核心增益介质。激光玻璃中通常掺杂有稀土金属离子,稀土金属离子的掺杂浓度是决定激光玻璃增益特性的重要参数。
通常,提高激光玻璃中的稀土掺杂浓度,有利于增加激发态上能级粒子数,从而提高激光输出功率和斜率效率,同时还有助于缩短激光腔长进而有利于器件的小型化和集约化。然而,当掺杂浓度增加到一定值时,离子间过强的相互作用一方面会增加交叉弛豫等能量传递过程,导致上能级寿命和发光强度等降低;另一方面也会导致玻璃容易发生分相或析晶现象,降低稀土金属离子在玻璃基体中的溶解度。在上述两种因素的共同作用下,激光玻璃的发光强度随掺杂浓度增加而产生先增后减的变化,即存在激光玻璃的发光强度最大时对应的最佳稀土掺杂浓度,称为激光玻璃中稀土猝灭浓度。传统技术中通常需要经过一系列不同掺杂浓度的梯度实验,以最终确定激光玻璃中稀土猝灭浓度。当玻璃基材或者掺杂的稀土金属离子发生改变时,都需要重新实验以确定稀土猝灭浓度。该方法存在周期长、效率低下以及成本高等问题,限制了激光玻璃的进一步发展。

在该实施例的一些示例中,激光玻璃的氧化物成分中含有多种能够与氧元素组成氧化物的元素,即除了氧元素之外,激光玻璃的玻璃基体中还含有两种或多于两种的元素。
在该实施例的一些示例中,获取备选化合物的步骤包括:基于第一性原理计算目标激光玻璃的基体组成元素中各种原子组合的形成能,并通过粒子群优化算法筛选出形成能小于0的原子组合,作为备选化合物。可以理解,基体组成元素中各种原子能够组成许多具有不同化学计量比的化合物,通过第一性原理计 算其形成能、并筛选形成能小0的原子组合,其作用在于确保该备选化合物能够由基体组成元素自发组成且稳定存在,从而在后续步骤中能够获取其中稀土元素的猝灭浓度。
在该实施例的一些示例中,备选化合物可以是复合氧化物,即备选化合物中含有多种能够与氧元素组成氧化物的元素,即除了氧元素之外,备选化合物中还含有两种或多于两种的元素。
在该实施例的一些示例中,目标激光玻璃中的氧化物成分为氧化钡和氧化硼,其中的基体组成元素为钡元素、硼元素和氧元素,根据第一性原理的计算以及粒子群优化算法的筛选,可以得出BaB2O4、BaB4O7和BaB8O13为形成能小于0的原子组合,则备选化合物为BaB2O4、BaB4O7和BaB8O13
在该实施例的一些示例中,目标激光玻璃中的氧化物成分为氧化锂、氧化钡和氧化硼,其中的基体组成元素为钡元素、硼元素、锂元素和氧元素,根据第一性原理的计算以及粒子群优化算法的筛选,可以得出BaB2O4、BaB4O7、BaB8O13、Ba2LiB5O10、BaLiB9O15、Li3B11O18、Li3B7O12、LiB3O5、Li2B4O7和LiBO2为形成能小于0的原子组合,则备选化合物为BaB2O4、BaB4O7、BaB8O13、Ba2LiB5O10、BaLiB9O15、Li3B11O18、Li3B7O12、LiB3O5、Li2B4O7和LiBO2
在该实施例的一些示例中,从备选化合物中选取至少一个邻近化合物的步骤包括:基于各氧化物成分在目标激光玻璃中的含量以及在备选化合物中的含量,选取与目标激光玻璃中各氧化物成分的含量最为接近的一种或多种备选化合物,作为邻近化合物。
其中,从备选化合物中选取邻近化合物的作用是筛选出氧化物成分与目标激光玻璃较为接近的备选化合物,从而使得选取出的邻近化合物的结构更为接近目标激光玻璃的“结构基元”,进而提高预测结果的准确程度。进一步地,该 含量指的是物质的量的含量。
在该实施例的一些示例中,可以从备选化合物中选取多个邻近化合物。例如,邻近化合物可以有两个、三个或者多于三个的数量。
为了便于计算,在该实施例中,设目标激光玻璃中含有m种氧化物成分,第i个氧化物成分在目标激光玻璃中的含量记为ai(1≤i≤m))。则各氧化物成分在目标激光玻璃中的含量依次记为a1~am。例如,假设目标激光玻璃中含有两种氧化物成分,则该两种氧化物成分在目标激光玻璃中的含量可以分别记为a1和a2。假设目标激光玻璃中含有三种氧化物成分,则该三种氧化物成分在目标激光玻璃中的含量可以分别记为a1、a2和a3
在该实施例的一些示例中,从备选化合物中选取邻近化合物的步骤为:获取相应的各氧化物成分在备选化合物中的含量,第i个氧化物成分在备选化合物中的含量记为bi,则各氧化物成分在一个备选化合物中含量的可以依次记为b1~bm。然后,可以通过式(1)计算各备选化合物的度量参数d,以d值最小的一种或多种备选化合物作为邻近化合物。
通过式(1)所示的计算方式能够定量且较为准确地表征氧化物成分整体在备选化合物中与其在目标激光玻璃中的含量之间的差异。其中,d值越小,则表示备选化合物与目标激光玻璃中的氧化物成分整体越接近,相应地预测结果的准确程度也就越高。
进一步地,在该实施例的一些示例中,在选取备选化合物作为邻近化合物时,可以预设度量阈值,将度量参数d值小于度量阈值的备选化合物选取为邻近化合物。
步骤S2,建立邻近化合物与目标激光玻璃之间的组成关系。
其中,组成关系包括组合形成目标激光玻璃的氧化物成分所需的各邻近化合物的含量。在该预测方法中,将步骤S1中选取的邻近化合物作为目标激光玻璃的“结构基元”,相应地,通过不同邻近化合物之间的含量搭配,能够使得其中的各氧化物成分含量与目标激光玻璃的各氧化物成分含量相同。
在该实施例的一些示例中,建立邻近化合物与目标激光玻璃之间的组成关系的步骤包括:述邻近化合物的数量为n,将各邻近化合物分别按照1~n标记,第i个氧化物成分在第j个邻近化合物中的含量记为bij(1≤j≤n)。将组成目标激光玻璃所含有的氧化物成分所需的第i个邻近化合物的含量记为xi。通过式(2)计算各邻近化合物的含量;
可以理解,式(2)表示矩阵运算,其中的b11~bm1表示第1个邻近化合物中的各氧化物成分的含量,b1n~bmn表示第m个邻近化合物中的各氧化物成分的含量,x1~xn表示所需的n个邻近化合物的含量。在式(2)所示的矩阵运算中,bij可以根据各邻近化合物的化学式直接得到,ai可以根据目标激光玻璃所含有的氧化物成分直接得到,则x1~xn可以经过式(2)的计算得到。
步骤S3,基于各邻近化合物的含量以及各邻近化合物中稀土元素的猝灭浓度进行加权计算,获得目标激光玻璃中稀土元素的预测猝灭浓度。
在该实施例中,“加权计算”指的是采用组成关系中各邻近化合物的含量作为权重,并将权重乘以相应的邻近化合物中稀土元素的猝灭浓度之后,进行加和计算,即能够得出目标激光玻璃中稀土元素的预测猝灭浓度。
在该实施例的一些示例中,邻近化合物中稀土元素的猝灭浓度的获取方式包括但不限于:制备稀土元素掺杂的邻近化合物并通过测试得到、查阅文献得到、基于已有结果进行推算得到。
在该实施例的一些示例中,稀土元素在第j个邻近化合物中的猝灭浓度为cj,并通过式(3)目标激光玻璃中稀土元素的预测猝灭浓度c*
可以理解,c*为目标激光玻璃中稀土元素的预测值。例如,当邻近化合物有两个时,n为2,则目标激光玻璃中稀土元素的预测猝灭浓度c*=x1c1+x2c2
可以理解,通过如步骤S1~步骤S3的预测方式,只需要获得作为基础的一些邻近化合物中稀土元素的猝灭浓度,就能够准确预测出各种不同的激光玻璃中稀土元素的猝灭浓度。并且,当邻近化合物中稀土元素的猝灭浓度均已知时,该预测方法仅需要通过计算过程即能够较为准确地得出激光玻璃中稀土元素的预测猝灭浓度。
本公开提供了一种激光玻璃中稀土猝灭浓度的预测方法,在该稀土猝灭浓度的预测方法中,基于各邻近化合物的含量与邻近化合物中稀土元素的猝灭浓度进行加权计算,以获得目标激光玻璃中稀土元素的预测猝灭浓度。该方法巧妙地将材料基因的研究理念应用于激光玻璃研究,创造性地提出将结构较为简单的邻近化合物作为结构较为复杂的激光玻璃的“结构基元”的构思,基于邻近化合物的含量以及邻近化合物中稀土元素的猝灭浓度预测目标激光玻璃中稀土元素的猝灭浓度。预测猝灭浓度的结果与实际的猝灭浓度之间误差较低,预测结果较为准确。并且该预测方法适用于多种激光玻璃体系,且可进一步拓展至其他激光玻璃体系,实现整个玻璃组成空间中稀土猝灭浓度的预测,能够有效提高获取稀土猝灭浓度的效率,缩短获取稀土猝灭浓度的周期并降低成本。
进一步地,如图2所示,本公开还提供了一种激光玻璃中稀土猝灭浓度的预测装置,其包括:
