Search for New Red Phosphors Using Genetic Algorithm-Assisted Combinatorial Chemistry

Abstract: A genetic algorithm was employed in association with high-throughput synthesis and characterization in an attempt to search for red phosphors with high photoluminescent intensity. A tetravalent manganese-doped alkali earth germanium oxide system, with an emission color close to a desirable deep red, was screened with the assistance of a genetic algorithm to pinpoint the phosphor exhibiting the highest photoluminescence. As the genetic algorithm was in progress, the PL intensity increased and maximized in the f… Show more

“…It is customary to adopt excessive (or deficient) elements in liquid solution-based syntheses. [6][7][8] The determination of relevant processing compositions is based on trial-error strategies in general solution-based syntheses. Thus, this cumbersome process is time-consuming and expensive.…”

“…[5] In this regard, the combination of GA and HTE results in a highly efficient system that enables the development of new materials and catalysts. [4,[6][7][8][9] For instance, we have identified some luminescent multi-compositional inorganic compounds using GACMS. [6][7][8][9] Error-free experimental processes are also very important in GACMS, because evaluation of an unknown objective function is performed by actual synthesis and subsequent characterization.…”

“…This means that an excessive amount of Ge was inevitable to achieve the NMG structure. It is customary to use such an excessive or deficient amount of elements in liquid solution-based syntheses (15)(16)(17)(18). The determination of relevant processing compositions is based on trial-error strategies in general solution-based syntheses.…”

“…[13][14][15][16][17][18][19][20][21][22][23][24][25][26][27] We have been working on combinatorial chemistry to search for luminescent materials spanning from a conventional to the heuristic approach, i.e., simple mixing to smart mixing during last few years. [20][21][22][23][24][25][26][27] After the implementation of genetic-algorithm-assisted combinatorial material science (GACMS) we reduced the cost and time by reducing both the size of the population and the number of generations required for satisfactory optimization. [24][25][26][27] However, it is unfortunate that the commercialization of materials through combinatorial chemistry was limited except for a few luminescent materials.…”
