In this study, we investigate the photoluminescence properties of Sm3+-doped yttrium orthophosphate (YPO4) phosphors synthesized using the coprecipitation method. X-ray diffraction and Fourier-transform infrared spectroscopy were used to examine the structure and vibrational properties of the synthesized phosphors. By analyzing diffuse reflectance spectra using the Kubelka–Munk theory, the optical bandgap was determined to be 4.03 eV, corresponding to the UV region. Photoluminescence spectra, obtained under 406-nm excitation, showed orange emission at 602 nm, attributable to the 4G5/2 → 6H7/2 transition of Sm3+ ions. Dipole–dipole interactions were responsible for the concentration-quenching effect, investigated using Dexter's hypothesis. Photometric and colorimetric investigations were performed to explore the emission behavior of the phosphors. The calculated CIE coordinates confirmed emission in the orange region, and photometric investigations revealed that the phosphor exhibited orange emissions under UV illumination.

The structure and morphological properties of Cys-PANI were confirmed from FTIR and scanning electron microscopy (SEM). Fluorescence quenching of bovine serum albumin (BSA) and human serum albumin (HSA) was carried out using different concentrations of the Cys-PANI oligomers. There was a slight difference in the static quenching of HSA as compared to BSA, which was attributed to the different structures of the two serum albumins. The quenching rate constant was found to increase with cysteine content in the polymer, showing that the loading of higher amount of Cys increased the solubility of the Cys-PANI oligomers. This led to electrostatic attraction between the water molecules shielding the serum albumins and the Cys-PANI oligomers. The docking studies confirmed the binding to be hydrogen bonding, π-alkyl and π-amide stacked interactions. The binding energy of the Cys-PANI oligomers with mole ratio 50:50 and 20:80 was found to be better as compared to the Cys-PANI oligomer.

The recommended method relies on quantifying the intensity of NAP's native fluorescence at 354.0 nm after excitation at 235.0 nm ensuring that ESO does not cause any interference. Whereas for ESO, which has no fluorescent activity, its determination was carried out by coupling with fluorogenic reagent, NBD-Cl, and the fluorescence intensity of the output of reaction was recorded at 538.0 nm, following excitation at 469.0 nm, with no interference from the NAP. Every factor influencing fluorescence intensity was examined.

Inspired by EPS's medical importance and the absence of native fluorescence of ESP, we introduce a sensitive fluorimetric method for detecting EPS in eye drops and artificial aqueous humor for the first time. The method presented here utilizes a well-known derivatization reaction called Hantzsch derivatization reaction to convert the nonfluorescent EPS drug to a fluorescent derivative.
