%X Arrays of single photon emitters with the same energy of luminescence are necessary for the development of quantum imformation technology. The studied epitaxial quantum dots have an undresired inhomogeneity of luminescence. Here, AxB1-xCyD1-y alloys of AC, AD, BC and BD compounds are presented as semiconductors in which non-random distribution of cations and anions may result in self-assembling of identical tetrahedral clusters. It can be due to the preference of AC and BD bonding over AD and BC one, a decrease of the strain energy or both of them. The self-assembling conditions of 1P4Ga clusters in AlN-rich AlxGa1-xPyN1-y alloys with Ga and phosphorus contents in the dilute and ultra dilute limits, correspondingly, are represented. All phosphorus atoms should be in 1P4Ga clusters at ~1000 oC if the Ga content reaches several percents. AlN-rich AlxGa1-xPyN1-y alloys with 1P4Ga clusters are promising semiconductors for fabrication of arrays of identical single photon emitters with the same energy of luminescence
