“…15 Table 4 presents pyroelectric coefficients and FOMs of several thin lms. [35][36][37][38][39][40][41][42][43][44][45] The ceramic-polymer composites combine polymeric properties such as mechanical exibility, formability, and low cost with the ceramic properties such as large p and excellent mechanical strength. These hybrids exhibit better pyroelectric properties over the individual constituent phase while possessing excellent mechanical strength, formability, and robustness of the polymer, which may someday be useful for IR detectors without supporting substrates.…”

Fe doped lithium niobate, LiNbO3 (LN), crystals were grown successfully by the Czochralski technique. Growth parameters were optimized to get a constant diameter crystal without using the automatic diameter control (ADC) system. A broad absorption band centered at 488 nm has been observed in the absorption studies due to 2eg and 2t2g transition. The significant red shift in UV absorption edges indicates a decrease in the Li/Nb ratio in the Fe doped LiNbO3 crystals. Energy dispersive analysis by X-ray (EDAX) shows that the crystal is doped successfully with the desired Fe concentration. Birefringence interferometry was used for quantitative assessment of the optical quality of the grown crystal.

“…[13][14][15]. LiNbO 3 is one of the classic pyroelectric materials, which is often used in IR detectors [16,17], and LiNbO 3 is expected to absorb energy quite uniformly across the IR [18]. Recently, pyroelectric material was applied in dispensing liquids on micrometer-and nanoscale by pyroelectrodynamic shooting.…”

A new atmospheric pressure ionization method termed pyroelectricity-assisted infrared laser desorption ionization (PAI-LDI) was developed in this study. The pyroelectric material served as both sample target plate and enhancing ionization substrate, and an IR laser with wavelength of 1064 nm was employed to realize direct desorption and ionization of the analytes. The mass spectra of various compounds obtained on pyroelectric material were compared with those of other substrates. For the five standard substances tested in this work, LiNbO3 substrate produced the highest ion yield and the signal intensity was about 10 times higher than that when copper was used as substrate. For 1-adamantylamine, as low as 20 pg (132.2 fmol) was successfully detected. The active ingredient in (Compound Paracetamol and 1-Adamantylamine Hydrochloride Capsules), 1-adamantylamine, can be sensitively detected at an amount as low as 150 pg, when the medicine stock solution was diluted with urine. Monosaccharide and oligosaccharides in Allium Cepa L. juice was also successfully identified with PAI-LDI. The method did not require matrix-assisted external high voltage or other extra facility-assisted set-ups for desorption/ionization. This study suggested exciting application prospect of pyroelectric materials in matrix- and electricity-free atmospheric pressure mass spectrometry research.
