Photoluminescence: Applications01:14

Photoluminescence: Applications

Photoluminescence offers a wide range of applications due to its inherent sensitivity and selectivity. This technique allows for both direct and indirect analyses of the analyte. Direct quantitative analysis is possible when the analyte exhibits a favorable quantum yield for fluorescence or phosphorescence. However, an indirect analysis may be feasible if the analyte is not fluorescent or phosphorescent, or if the quantum yield is unfavorable. Indirect methods include reacting the analyte with...
Fluorescence and Phosphorescence: Instrumentation01:25

Fluorescence and Phosphorescence: Instrumentation

Fluorometers and spectrofluorometers are two types of instruments used for measuring molecular fluorescence. These instruments differ in how they select excitation and emission wavelengths and the type of light sources they utilize. Fluorometers use absorption interference filters to choose excitation and emission wavelengths. The excitation source in a fluorometer is typically a low-pressure mercury vapor lamp that emits intense lines distributed throughout the ultraviolet and visible regions.
Flame Photometry: Overview01:02

Flame Photometry: Overview

Flame photometry, also known as flame emission spectrometry, is a technique used for the qualitative and quantitative analysis of elements present in a sample using a flame as the source of excitation energy. The concept of flame photometry was realized in the early 1860s by Kirchhoff and Bunsen, who discovered that specific elements emit characteristic radiation when excited in flames. The first instrument developed for this purpose was used to measure sodium (Na) in plant ash using a Bunsen...

Area of Science:

  • Materials Science
  • Optical Diagnostics
  • Thermodynamics

Background:

  • Phosphor thermometry measures surface temperature using luminescence from doped ceramics.
  • Existing systems using Q-switched lasers (10 Hz) are limited to time scales >100 ms.
  • This limits application in rapidly changing thermal environments.

Purpose of the Study:

  • To develop and demonstrate a high-speed phosphor thermometry system.
  • To enable temperature measurements at millisecond or faster timescales.
  • To characterize a new phosphor material for high-repetition rate applications.

Main Methods:

  • Employed a highly repetitive laser system (kHz regime) for phosphor excitation.
  • Utilized a fast-decaying phosphor material.
  • Characterized phosphor temperature-lifetime properties and measurement precision.
  • Investigated laser power effects on phosphor coatings.
  • Demonstrated the system in an optically accessible internal combustion engine.

Main Results:

  • Achieved a 6 kHz measurement repetition rate (1 sample/crank angle degree at 1000 rpm).
  • Successfully measured temperatures in a highly transient internal combustion engine environment.
  • Characterized material properties and validated measurement precision.

Conclusions:

  • The developed high-speed phosphor thermometry system overcomes previous temporal limitations.
  • This technique is suitable for analyzing rapid temperature changes in dynamic systems.
  • The system offers a novel diagnostic tool for internal combustion engine research and other transient thermal applications.
