研究目的
Investigating the potential of B4C submicrometer spherical particles fabricated by pulsed laser melting in liquid (PLML) as novel nano-heater particles that overcome the limitations of gold nanoparticles, such as limited wavelength range and low melting point.
研究成果
B4C submicrometer spherical particles fabricated by PLML can act as effective nano-heaters across a wide wavelength range (300–1100 nm) and at high temperatures (over 2000 K), offering a promising alternative to gold nanoparticles for space-selective heating applications.
研究不足
The study is limited by the size fluctuation of PLML-fabricated B4C particles and the assumption of negligible heat loss from laser-heated particles to the surrounding environment, which may not fully account for practical heat dissipation scenarios.
1：Experimental Design and Method Selection:
The study utilized PLML to fabricate B4C submicrometer spherical particles and examined their performance as nano-heaters by laser irradiation.
2：Sample Selection and Data Sources:
Commercially available raw boron nanoparticles were dispersed in ethanol and irradiated by a nanosecond pulsed laser to form B4C particles.
3：List of Experimental Equipment and Materials:
A nanosecond pulsed laser (pulse width: 7 ns), ethanol, boron nanoparticles, polystyrene, TeO2 and SrTiO3 substrates.
4：Experimental Procedures and Operational Workflow:
B4C particles were spread on substrates and irradiated with lasers of different wavelengths to observe morphological changes indicating heating.
5：Data Analysis Methods:
The attained temperature of particles was estimated based on morphological changes of materials in contact with B4C particles and compared with theoretical calculations.
