Well-crystallized Bi-Te single crystals with different ratios were grown in vertical Bridgman method. Broadband emission was detected in 1900-3000 nm. Annealing treatment and XPS test revealed the emission center might be Bi clusters. The forming process and energy level transition of Bi clusters were given in this paper.
