Facility Features, Working Principle and Specifications

Features Working Principle

Features : 

Spectrograph equipped with a research-grade microscope capable of producing Raman (wavenumber transfer 50 to 4000 cm-1) and PL (330 nm to 1.6 microns).

Spectral Range of spectrometer: 200 nm – 1600 nm

Microscope Objective-1) Normal WD-5X,20X,100X ; 2) Long WD-50X ; 3) NUV-15X & 40X

Imaging/Mapping –XYZ motorized and computer-controlled mapping stage with a minimum travel distance of 110x75x25 mm with a resolution of 50x50x10 nm. Scanning step size for 2D mapping to be better than 50 nm.

Body Specification

Temperature requirement : 10 to 300 K (CCR), Room temperature to 1500 K (Furnace)

Other capabilities- Low wavenumber measurements (down to 15cm-1 with 532 nm laser), polarization study with 532 nm laser, remote probe fibre coupling with 532 nm laser.

Instructions for Registration, Sample Preparation, User Instructions, Precautionary Measures and Charges

Instructions for Registration

Mention the following -

  1. Type of analysis and number of samples
  2. Excitation laser wavelength and spectral range required
  3. Temperature range required and interval between temperature readings (in case of temperature-dependent analysis) 
  4. Polarization angle intervals (in case of polarization-dependent analysis) 
  5. Time intervals (in case of time-dependent analysis)

 

Instruction for Sample Preparation

• Maximum size of sample which can be placed on the microscope stage is 5cm x 5cm x 3cm.

• For temperature-dependent studies sample size should be less than 3mm x 3mm x 1mm.

• If possible, use of coolants/lubricants should be avoided when resizing the samples.

User Instructions and Precautionary Measures

• Solid samples should be dry and be able to withstand exposure to high intensity laser beam without heating up which may lead to sample deformation or emission of fumes.

• For temperature-dependent analysis sample must be able to withstand temperatures at which analysis is to be done.

• System’s optical microscope may not be able to acquire any data from particles/structures having size in nanometer range.
