Tunable broad-band white-light emission in two-dimensional (110)-oriented lead bromide perovskite (C₃H₈N₆)[PbBr₄]: optical, electronic and luminescence properties

Abstract

Newly, room temperature phosphorescence (RTP) in 2D hybrid perovskites has been proved due to the energy transfer from inorganic sheets to the conjugated organic cations harnessing the triplet states. So...

Organically tuned white-light emission from two zero-dimensional Cd-based hybrids

“…81,82 On the other hand, the Br À /p + interactions promote the ISC through triplet state harvesting and then, generate the RTP. 17,50 In our recent paper that studied the RTP phosphorescence from the 110-oriented perovskite (C 3 H 8 N 6 )[PbBr 4 ], 17 we theoretically demonstrated the effect of the Br À /p + interaction on the triplet states of the protonated organic ring, containing heteroatoms, and the emission from the triplet states was conrmed. Hence, the coexistence of these two efficient strategies previously used for RTP stabilization suggests the RTP nature of the emission from CdACP.…”

“…In addition to their pertinent magnetic, 1-8 catalytic [9][10][11][12] and biological 9,[13][14][15] properties, organic-inorganic molecular hybrid materials (OIMHMs) exhibit excellent performance in solid-state emitter sources 16,17 as well as in photovoltaic solar cells. [18][19][20][21] Due to their wide band gap energy, low dimensional hybrid compounds are effectively used for optoelectronic devices such as light emitting and diode photo-detectors.…”

“…In fact, such interaction enhance the SOC (spin orbit coupling) and then, promote the ISC (intersystem crossing) harnessing the triplet excitons. 17,[43][44][45] Recently, this new strategy was successfully used to achieve RTP in OIMHMs. [46][47][48] The zerodimensional (0-D) Cd-based OIMHMs demonstrate relevant photoluminescent properties.…”

A Cd-based perovskite with optical-electrical multifunctional response

“…The 2D perovskites are formed by n-layered inorganic frameworks, and organic cations interspersed within two adjacent inorganic layers. The extraordinary tunable structures endow these perovskites with diverse properties, such as phase transition, [19][20][21][22][23][24] photoluminescence (PL), [25][26][27] narrow energy band gap, [28][29][30] optoelectronic, [31][32][33] and ferroelastic [34][35][36] or ferroelectric properties. [37][38][39][40][41][42][43] In the past few decades, there have been plenty of reports on the above-mentioned materials.…”

Zn2+ and Cu2+ doping of one-dimensional lead-free hybrid perovskite ABX3 for white light emission and green solar cell applications

“…[1][2][3][4][5][6][7][8][9][10] Organic-inorganic metal halide-based perovskites (OIMHP) are acclaimed for their electrical and opto-electrical properties. [11][12][13][14][15][16][17][18][19][20] In fact, because of their low band gap energies around 1.5 eV, the three dimensional (3-D) OIMHP are widely used in photovoltaic solar cells (SCs). The most famous 3-D OIMHP are the lead (II)-based MAPbX 3 (MA = CH 3 NH 3 ; X = I, Br or Cl halogens) whose performance in photon conversion has been proven.…”
