Zusammenfassung:	The results of research and development of a new tellurium-loaded liquid scintillator (LS) based on linear alkylbenzene (LAB) for large-scale detectors to search for and study neutrinoless double beta decay are presented. It has been proposed for the first time to use a complex compound of diphenyltellurium oxide and di-(2-ethylhexyl)phosphoric acid as a tellurium-loaded additive. The dependences of the light yield and transparency on the tellurium concentration, the effect of a secondary scintillation solvent on the light yield, and the stability of the properties of tellurium-loaded LSs have been studied.
