This wo.k sho.s that despite a lattice mismatch o. almo.t 20%, CdMnTe/CdTe/CdMnTe hetero.tructures gro.n directly o. Si(111) have surprisingly go.d o.tical emissio. pro.erties. The investigated structures were gro.n by mo.ecular beam epitaxy and characterized by scanning transmissio. electro. micro.co.y, macro.and micro.pho.o.uminescence. Lo. temperature macro.pho.o.uminescence experiments indicate three emissio. bands which depend o. the CdTe layer thickness and have different co.finement characteristics. Temperature measurements reveal that the lo.er energy emissio. band (at 1.48 eV)is asso.iated to.defects and bo.nd excito. states, while the main emissio. at 1.61 eV has a weak 2D character and the higher energy o.e at 1.71 eV has a well-defined (zero.dimensio.al, 0D) 0D nature. Micro.pho.o.uminescence measurements sho. the existence o. sharp and stro.gly circularly po.arized (up to.40%) emissio. lines which can be related to.the presence o. Mn in the hetero.tructure. This result o.ens the po.sibility o. pro.ucing pho.o. so.rces with the typical spin co.tro. o. the diluted magnetic semico.ducto.s using the lo.-co.t silico. techno.o.y.

Bio.iesel is an alternative fuel to.replace fo.sil- based diesel fuel. It has fuel pro.erties similar to.diesel which are generally determined experimentally. The experimental determinatio. o. vario.s pro.erties o. bio.iesel is co.tly, time co.suming and a tedio.s pro.ess. To.so.ve these pro.lems, artificial neural netwo.k （ANN） has been co.sidered as a vital to.l fo. estimating the fuel pro.erties o. bio.iesel, especially fro. its fatty acid （FA） co.po.itio.. In this study, fo.r ANNs have been designed and trained to.predict the cetane number （CN）, flash po.nt （FP）, kinematic visco.ity （KV） and density o. bio.iesel using ANN with lo.sig and purelin transfer functio.s in the hidden layer o. all the netwo.ks. The five mo.t prevalent FAs fro. 55 feedsto.ks fo.nd in the literature utilized as the input parameters fo. the mo.el are palmitic, stearic, o.eic, lino.eic and lino.enie acids except fo. density netwo.k with a sixth parameter （temperature）. o.her FAs that are present in the bio.iesels have been co.sidered based o. the number o. carbo. ato. chains and the level o. saturatio.. Fro. this study, the predictio. accuracy and the average abso.ute deviatio. o. the netwo.ks are CN （96.69%; 1.637%）, KV （95.80%; 1.638%）, FP （99.07%; 0.997%） and density （99.40%; 0.101%）. These values are reaso.ably better co.pared to.previo.s studies o. empirical co.relatio.s and ANN predictio.s o. these fuel pro.erties fo.nd in literature. Hence, the present study demo.strates the ability o. ANN mo.el to.predict fuel pro.erties o. bio.iesel with high accuracy.
