Fig. 2. High-density integrated lasers and broad wavelength-tunable single-mode lasers at high temperature based on CQDAMs.

Caption

a, Schematic diagram of the mass-produced integrated CQD microlasers working at high temperature. b, Real-color image of the different CQD-based silica matrix samples excited by ultraviolet light. c, Corresponding internal enlarged microscopic image under high excitation condition. The red dots are the lasing CQDAMs at 400 K. d, Multicolor single-mode lasers coming from CQDAMs of different compositions and/or sizes, the lasing energies of which cover the entire visible range.
