Enhanced Thermal Stability of Halide Perovskite CsPbX3 Nanocrystals by a Facile TPU Encapsulation

“…At low temperatures, two unencapsulated samples are relatively stable. A loss of about 5–7 wt% in the temperature of 150–300 °C was detected which can be attributed to the volatilization of oleic acid (OA) on the surface of the material …”

Lead‐Free Highly Efficient Blue‐Emitting Cs3Cu2I5 with 0D Electronic Structure

“…However, their PLQYs are not as high as QDs, and the toxicity of Pb still remains an issue to be resolved. Against this background, the use of low‐dimensional materials is of great interest because the intrinsic QCE is expected to lead to high PLQY . Furthermore, compared to QDs, dense thin films can be more easily fabricated.…”

“…A comparison of the electronic structures between conventional 3D and 0D luminescent materials will help achieve this goal (cf. 3D CsPbBr 3 : exciton binding energy ≈18 meV, 0D Cs 4 PbBr 6 : ≈240 meV) . In the case of 3D perovskite materials such as CsPbX 3 , the conduction band maximum (CBM) originates mainly from Pb 6p orbitals, while the valence band maximum (VBM) originates from the admixed Pb 6s and I 5p orbitals.…”

Efficient Photon Recycling and Radiation Trapping in Cesium Lead Halide Perovskite Waveguides

“…It relies on a high radiative efficiency in CsPbBr3 perovskite microwires and provides crucial information about the potential impact of photon recycling and waveguide trapping on optoelectronic properties of cesium lead halide perovskite materials. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 3 Solution-processed organic-inorganic hybrid perovskite-based semiconductors have rapidly progressed as versatile and promising materials for low-cost and high-performance optoelectronics applications in the past five years [1][2][3][4][5][6][7][8][9][10][11] due to their remarkable light absorption 12 , long carrier diffusion length 12,13 , controllable dimensionalities [14][15][16][17][18][19][20][21] and tunable bandgaps. 22 Recently, all inorganic CsPbX3 (X=Br  , I  or Cl  ) perovskites have attracted part...…”
