2D Material and Perovskite Heterostructure for Optoelectronic Applications

“…These semiconductor devices that convert optical signals into electrical ones have wide applications in the areas of renewable energy, imaging systems, biomedical devices, and optical communications [1][2][3][4]. Over the past few decades, tremendous efforts have been made persistently to enhance the efficiency and stability of the devices through synthesizing high-quality materials [5][6][7][8][9][10][11][12], designing novel device structures, engineering interfaces [13], and employing encapsulation with polymer and inorganic glass [14,15].…”

Selectively Tunable Luminescence of Perovskite Nanocrystals Embedded in Polymer Matrix Allows Direct Laser Patterning

“…They include surface engineering, [21][22][23] doping, [24,25] and matrix encapsulation. The latter can be performed by incorporating the NCs in various robust inorganic matrices, such as salts, [26] silica, [27] glass, [28,29] and zeolite, [30] or in polymers. The encapsulation of perovskite NCs in polymer matrices provides the advantage of efficient protection in combination with the processability of the NCs and polymer solutions by dropcasting, spray-and spin-coating, and other film-forming technologies promising for optical applications.…”

Spectral Tuning, Stabilities under External Exposures, and Spontaneous Enhancement of Emission Intensity in Grown‐into‐Glass All‐Inorganic Metal Halide Perovskite Nanocrystals

“…[11] During the last three to five years, strategies involving the growth and stabilization of MHPs nanocrystals (NCs) like CsPbBr 3 into a glass matrix by use of an in situ crystallization route [29] or postmelting procedure [30] have demonstrated great improvements in terms of luminescent quantum yields, waterresistance, thermal-and long-term photostability in comparison with the glass-unprotected (hereafter GU) counterparts. [12,[29][30][31][32][33][34] The benefits in these concerns are, on the one hand, to keep the NCs particles away from each other and/or from the glass edge and may, on the other hand, sustain the optimized micro-or nanostructure under external exposures for a relative long term. That is, each MHPs particle crystallized in the glass matrix is expected to keep a relatively fixed location in the glass matrix, without being moved around easily with the change of the external environments such as thermal stimuli.…”

“…This also indicates that such issues, if they cannot be addressed well, would worsen the PL and/or structural properties of PMs and thus, are not good for and may even be detrimental to, such as, the lighting device fabrication.
