Rectangular samples of film blends (24 mm2, 6.5 mg, 120–150 µm) containing ILs at concentrations of 0.5, 1, and 5 wt% were immersed in 3 mL of PBS and kept at 37 °C for 24 h. A Jasco V-770 UV–vis–NIR spectrophotometer (Jasco Europe S.R.L., Cremella, LC, Italy) was used to determine the release kinetics. Aliquots were collected at specific interval times (1–24 h), and the optical absorption at 210 nm was measured. Experiments were performed in triplicates, and data are presented as the mean ± S.D.

Absorption spectra of perovskite films were tested using a V-770 UV/VIS/NIR spectrophotometer (Jasco, Japan). Use a fluorescence spectrophotometer model Hitachi F-7000 (Tokyo, Japan) to test the photoluminescence (PL) spectrum of perovskite films. X-ray diffraction (XRD) patterns of perovskite films were tested using a PANalytical X’Pert PRO MRD diffractometer (Almelo, The Netherlands) using CuKα (λ = 1.5418 Å) radiation source. The surface morphologies and high-resolution transmission electron microscopy (TEM) image of the perovskite films and PeQDs were observed using a ZEISS Sigma field emission scanning electron microscope (FESEM) instrument (ZEISS, Germany) and a JEM-2100F transmission electron microscope instrument (JEOL, Japan), respectively. The photocurrent–voltage (J–V) curves of the PeQDs/triple-cation PeSCs were obtained by using a MFS-PV-Basic solar simulator (Hong-Ming Technology Co., Ltd., Taiwan) with a Keithley 2420 source meter under illumination of AM 1.5G simulated sunlight at 100 mW cm−2, calibrated by a NREL PVM-894 standard silicon reference cell (PV Measurements Inc., USA). External quantum efficiency (EQE) was tested by LSQE-R QE system (LiveStrong Optoelectronics Co., Ltd., Taiwan) equipped with a LAMBDA 35 UV–VIS-NIR spectrophotometer (PerkinElmer, USA) and a XES-204S 150 W xenon lamp (San-Ei Electric Co., Ltd., Japan) as a light source.

The thickness and refractive indices of the prepared glasses play an important role in the estimation of luminescence parameters. So, the refractive indices (n) were determined by the Abbe's refractometer using sodium vapour lamp as a source. The optical absorption spectra were recorded using Jasco V-770 UV-VIS-NIR spectrophotometer. The luminescence and decay measurements were performed using FLS-980 fluorescence spectrometer with xenon flash lamp as a source. All the spectral measurements were carried out at room temperature.

Adsorption studies were carried out on all four synthesized CeO2 samples (1 g L−1) using Congo red as the model pollutant at a concentration of 20 mg L−1. The adsorption experiments were carried out in magnetically stirred glass vessels at the ambient pH of the Congo red solution. At regular contact intervals, samples were withdrawn, centrifuged and analysed using a Jasco V-770 UV-vis-NIR spectrophotometer. To evaluate the selectivity, adsorption analyses were performed with methylene blue and methyl orange also. The effect of dye concentration and pH on adsorption activity was evaluated by varying the initial dye concentrations (10, 15, 20, 25 and 30 mg L−1) and by carrying out adsorption studies under 3 different pH conditions (3, 6.5 (ambient pH) and 10). Besides this, the pH of the point of zero charge (pHPZC) of the adsorbent material was determined using the pH drift method.45 (link)

QDs were precipitated with hexane:ethanol (1:3) and resuspended in TCE for optical characterization; TCE was chosen to minimize solvent absorbance in the SWIR.13 (link),45 (link) Absorbance spectra of the QDs were measured with a Jasco V-770 UV-Vis-NIR spectrophotometer. Photoluminescence (PL) spectra of the core/shell QDs were recorded with a FLS1000 photoluminescence spectrometer (Edinburgh Instruments, UK) equipped with a near infrared photomultiplier tube (NIR-PMT) with sensitivity up to 1700 nm. The same spectrometer was also used to measure the absolute quantum yield (QY) values of the PbS/CdS QDs. Cuvettes containing dilute QD samples (~0.5 abs at excitation) in TCE were placed in an integrating sphere and excited with a Xenon arc lamp excitation source with 10 nm slitwidth at 808 nm, selected to match the excitation wavelength used in the imaging studies. With pure TCE in the same sample holder used in the background scan, the absolute QY was calculated with Fluoracle® (Edinburgh Instruments, UK) software.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
