title: Luminescence of AgCl:Ho nanocrystals and applied in IR LEDs used as active material.
abstract: 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 5F5 --> 5I7, 5I6 --> 5I8 and SF5 --> 5I6 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.
