AgCl:Ho nanocrystals were synthesized in the aqueous medium from readily available precursors. The construction and morphology of AgCl:Ho nanocrystals were studied. Vis-NIR absorption, excitation and photoluminescence emission spectra of AgCl:Ho nanocrystals were investigated at room temperature. PL spectra of AgCl:Ho nanocrystals with different molar ratio of Ho ions excited at 448 nm all have broadened emission bands centered around 1000, 1210 and 1540 nm, which can be attributed to the F-5(5) -> I-5(7), I-5(6) -> I-5(8), and F-5(5) -> I-5(6) energy transition, respectively. Moreover, AgCl:Ho nanocrystals used as an active material were combined with InGaN diode to fabricate the IR LED which possesses the effective near infrared emission.
