interest in using plasmonic nanoparticles as thermal nano sources with the ability to be controlled remotely by light, which has led to the emergence of thermoplasmonics science. In this regard, nanoparticles with different shapes, compositions, and materials can create limited heat generation at the nanoscale. Therefore, in this article, the plasmonic and thermoplasmonic properties of asymmetric hexagonal heterodimer nanoparticles of Ag-Au, Cu-Ag, and Cu-Au compositions have been investigated. The isosbestic points and the coupling energy due to the gap created in the plasmonic modes of the absorption spectrum due to the change in the polarization of the light have been investigated and calculated. The obtained results show that with the combination of heterogeneous binary nanoparticles of silver and copper in light polarization parallel to the dimer axis, the electric field can be strengthened up to 293 times, and the highest temperature change in Ag-Au heterogeneous binary nanoparticles with a value of </span><m:omath><i><span cambria="" math="" style="font-family:"><m:r>∆</m:r></span></i><m:ssub><m:ssubpr><span cambria="" math="" style="font-family:"><span style="font-style:italic"><m:ctrlpr></m:ctrlpr></span></span></m:ssubpr><m:e><i><span cambria="" math="" style="font-family:"><m:r>T</m:r></span></i></m:e><m:sub><i><span cambria="" math="" style="font-family:"><m:r>max</m:r></span></i></m:sub></m:ssub><i><span cambria="" math="" style="font-family:"><m:r>=417℃</m:r></span></i></m:omath><span style="font-size:11.0pt"><span style="line-height:120%"><span calibri="" style="font-family:"><span style="position:relative"><span style="top:5.5pt"><img alt="" id="_x0000_i1025" src="data:image/png;base64,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" style="width:1in; height:15.4pt" > </span></span></span></span></span><span new="" roman="" style="font-family:" times="">&nbsp;in L polarization is related.</span><span lang="AR-SA" dir="RTL" style="font-family:"B Nazanin""></span></span></span></span></span><br> &nbsp; ترموپلاسمونیک؛ نانوذرات دوتایی ناهمگن؛ انرژی کوپل شدگی؛ نقاط ایزوبستیک Thermoplasmonics, Heterodimer nanoparticles, coupling energy, isosbestic points 50 61 http://jmrph.khu.ac.ir/browse.php?a_code=A-10-280-1&slc_lang=fa&sid=1 fahimeh noori فهیمه نوری F.noori3305@gmail.com 10031947532846001159 10031947532846001159 Yes Qom University دانشگاه قم Abbas Azarian عباس آذریان Azarian@Qom.ac.ir 10031947532846001160 10031947532846001160 No Qom University دانشگاه قم
