High-Q Bismuth-Silicate Nonlinear Glass Microsphere Resonators

open access: yesIEEE Photonics Journal, 2012
The fabrication and characterization of a bismuth-silicate glass microsphere resonator has been demonstrated. At wavelengths near 1550 nm, high-modes can be efficiently excited in a 179-μm diameter bismuth-silicate glass microsphere via evanescent

Photothermal Interferometry Gas Sensor Based on the First Harmonic Signal

open access: yesIEEE Photonics Journal, 2018
Photothermal interferometry (PTI) incorporated with wavelength modulation spectroscopy is a typical ultrasensitive spectroscopic technique for trace gas detection. In this paper, to our best knowledge, we demonstrate that the first harmonic signal is the

Squaraine nanoparticles for optoacoustic imaging-guided synergistic cancer phototherapy

open access: yesNanophotonics, 2023
The unique optical properties of squaraine dyes make them promising for cancer phototheranostics, but the reported squaraines for in vivo treatments mainly rely on their photothermal effect, where monotherapy cannot achieve the desired therapeutic effect.

Colloidal CuFeS2 Nanocrystals: Intermediate Fe d-Band Leads to High Photothermal Conversion Efficiency [PDF]

open access: yes, 2016
We describe the colloidal hot-injection synthesis of phase-pure nanocrystals (NCs) of a highly abundant mineral, chalcopyrite (CuFeS2). Absorption bands centered at around 480 and 950 nm, spanning almost the entire visible and near infrared regions ...
