A high performance CsPbBr3 microwire based photodetector boosted by coupling plasmonic and piezo-phototronic effects

A Flexible Plasmonic-Membrane-Enhanced Broadband Tin-Based Perovskite Photodetector

“…The highest photocurrent EF of 6.5-fold is obtained at 410 nm for the perovskite photodetector utilizing the Ag NPs/5 nm Al 2 O 3 hybrid structure as compared to its counterpart without a Ag NP membrane, which is substantially larger than many other metal nanostructure-enhanced perovskite photodetectors (Table S1). 32,39,43,51 As shown in Figures S9 and S10, the maximum values of the detectivity and responsivity are achieved at the incident light of 410 nm, which matches well with the plasmonic resonance of the Ag NPs membrane. In addition, the time-resolved photocurrent response in Figure 4e indicates that the rise and the fall times of the optimized photodetector are 50 and 51 ms, respectively.…”

A high-responsivity CsPbBr3 nanowire photodetector induced by CdS@CdxZn1−xS gradient-alloyed quantum dots

“…5(c). 13,15,28,38,46,[59][60][61]66,67,69,[71][72][73] The detailed performances of related photodetector devices are listed in Table S2 (ESI †). Compared with the most carefully designed individual CsPbBr 3 wire and hybrid photodetectors, the performance of our photodetectors modified with QDs has remarkable advantages.…”

“…The photoelectric conversion efficiency obtained in this work under a 5 V bias voltage is much greater than that of most present CsPbBr 3 -based photodetectors, even at a much higher bias voltage. 13,38,[59][60][61][64][65][66][67][68][69][70][71][72][73][74][75] In addition, the detectivity (D*) of the CdS@Cd x Zn 1Àx S gradient-alloyed QD-decorated CsPbBr 3 photodetector is increased to 1.62 Â 10 13 Jones, and the response time is reduced to 330 ms. In consequence, a physical model based on band energy theory was developed to illustrate the physical mechanism of these unique enhancement phenomena.…”

Lanthanide-doped inorganic halide perovskites (CsPbX3): novel properties and emerging applications

“…5,6 Because of the direct bandgap, high absorption coefficient, high mobility, long carrier lifetime, costeffectiveness, etc., the all-inorganic cesium-lead halide perovskites (CsPbX 3 , where X = Cl, Br, and I) have been considered as rising stars for photovoltaic applications. [7][8][9][10][11] They are also used in making colored and white LEDs, [12][13][14][15] fluorescence sensors, 16 oxygen detection sensors, 17 gas sensors, 18 humidity sensors, 19 field-effect transistors, 20,21 filter-free color image sensors, 22 display applications, 23 photodetectors, [24][25][26] spectro-chemical probes, explosive detectors, 27 laser fabrication, 28 X-ray detection, 29,30 etc. In this review, we mainly discuss the basics of halide perovskites, including the major advantages and challenges of halide perovskites.…”
