Introducing of impurity ions into semiconductor nanocrystals can improve their photoluminescence quantum efficiency through energy transfer and enhance their applicability towards light-emitting devices. In this work, Mn doped CsPbCl3 and CsPbCl3-Br-x(x) perovskite nanocrystals were prepared in glass through melt-quenching and subsequent thermal treatment. Both Mn doping concentration and thermal treatment conditions affected the growth and resultant band edge emission of perovskite nanocrystals, enabling tunable photoluminescence ranging from UV to blue. In addition to UV-blue band edge emission from these Mn-doped perovskite nanocrystals, red emission from Mn ions was activated through efficient energy transfer from perovskite nanocrystals. Intensity ratio between the band edge emission of perovskite nanocrystals and red emission of Mn ions was also tunable by varying the Mn doping concentration and heat-treatment conditions, covering a wider color gamut. Along with the good chemical and mechanical properties of glass matrix, these Mn-doped cesium lead halide perovskite nanocrystal embedded glasses have potentials for applications in light emitting devices.
